PROMOÇÃO

frequently modified. recovery.signal and standby.signal files are now used to switch into non-primary mode. Allow pg_upgrade to use the file system's cloning feature, if there is one (Peter Eisentraut). Split the pg_statistic_ext catalog into two catalogs, and add the pg_stats_ext view of it (Dean Rasheed, Tomas Vondra). Initialize and start database service. This allows customization of the collation rules in a consistent way across all ICU versions. This change adds a VACUUM command option INDEX_CLEANUP as well as a table storage option vacuum_index_cleanup. Previously, CTEs were never inlined and were always evaluated before the rest of the query. Partitioning. using LLVM, introduced in PostgreSQL 11, is now enabled by default. will now use “C”-locale comparison semantics by default, rather than the database's default collation as before. Common table expressions, also known as WITH queries, can now be PostgreSQL 12 that offer performance and space management gains that our users Allow control of the auto_explain log level (Tom Dunstan, Andrew Dunstan), Update unaccent rules with new punctuation and symbols (Hugh Ranalli, Michaël Paquier), Allow unaccent to handle some accents encoded as combining characters (Hugh Ranalli), Allow unaccent to remove accents from Greek characters (Tasos Maschalidis), Add a parameter to amcheck's bt_index_parent_check() function to check each index tuple from the root of the tree (Peter Geoghegan), Improve oid2name and vacuumlo option handling to match other commands (Tatsuro Yamada). The options are --min-xid-age and --min-mxid-age. Swap the ports for the old and new PostgreSQL versions. The function is pg_ls_archive_statusdir(). Allow pg_rewind to disable fsync operations (Michaël Paquier), Fix pg_test_fsync to report accurate open_datasync durations on Windows (Laurenz Albe), When pg_dump emits data with INSERT commands rather than COPY, allow more than one data row to be included in each INSERT (Surafel Temesgen, David Rowley). Fix assorted bugs in XML functions (Pavel Stehule, Markus Winand, Chapman Flack). This release This feature allows TCP/IP connections to be encrypted when using GSSAPI authentication, without having to set up a separate encryption facility such as SSL. Disallow non-unique abbreviations in psql's \pset format command (Daniel Vérité). For example, in PostgreSQL 12.1 12 is the main version and 1 is the additional version. Also improve the error message in such cases. community of thousands of users, contributors, companies and organizations. The --clone option has the advantages of --link, while preventing the old cluster from being changed after the new cluster has started. Pandoc produces better output than lynx and avoids some locale/encoding issues. Notably, printf understands %m everywhere; on Windows, strerror copes with Winsock error codes (it used to do so in backend but not frontend code); and strerror_r always follows the GNU return convention. This allows some optimizations that previously would not have been applied in the presence of security barrier views or row-level security. Now, whenever extra_float_digits is more than zero (as it now is by default), only the minimum number of digits required to preserve the exact binary value are output. Add a WHERE clause to COPY FROM to control which rows are accepted (Surafel Temesgen). exit. Pandoc version 1.13 or later is required. for the GiST, GIN, and SP-GiST index types, the ability to create covering Include partitioned indexes in the system view pg_indexes (Suraj Kharage), Add psql command \dP to list partitioned tables and indexes (Pavel Stehule), Improve psql \d and \z display of partitioned tables (Pavel Stehule, Michaël Paquier, Álvaro Herrera), Fix bugs that could cause ALTER TABLE DETACH PARTITION to leave behind incorrect dependency state, allowing subsequent operations to misbehave, for example by not dropping a former partition child index when its table is dropped (Tom Lane), Improve performance and space utilization of btree indexes with many duplicates (Peter Geoghegan, Heikki Linnakangas). Parse libpq integer connection parameters more strictly (Fabien Coelho). ii postgresql 12+214 all object-relational SQL database (supported version) ii postgresql-11 11.7-0ubuntu0.19.10.1 amd64 object-relational SQL database, version 11 server ii postgresql-12 12.2-4 amd64 object-relational SQL database, version 12 server ii postgresql-client 12+214 all front-end programs for PostgreSQL (supported version) ii postgresql … including being featured for the second year in a row as the Remove obsolete pg_attrdef.adsrc column (Peter Eisentraut). In previous releases, using an incorrect integer value for connection parameters connect_timeout, keepalives, keepalives_count, keepalives_idle, keepalives_interval and port resulted in libpq either ignoring those values or failing with incorrect error messages. Patches that manually assign OIDs for new built-in objects (such as new functions) should now randomly choose OIDs in the range 8000—9999. Specifically, CTEs are automatically inlined if they have no side-effects, are not recursive, and are referenced only once in the query. The fundamental indexing system PostgreSQL uses is called a B-tree, which is a type of index that is optimized for storage systems. Change SQL-style substring() to have standard-compliant greediness behavior (Tom Lane). The core of the PostgreSQL object-relational database management systemis available in several source and binary formats. Version 12 contains a number of changes that may affect compatibility with previous releases. Progress is reported in the pg_stat_progress_create_index system view. Cause DROP IF EXISTS FUNCTION/PROCEDURE/AGGREGATE/ROUTINE to generate an error if no argument list is supplied and there are multiple matching objects (David Rowley). indexes (the INCLUDE clause) Add EXPLAIN option SETTINGS to output non-default optimizer settings (Tomas Vondra). Note that this support is not built by default, but has to be selected explicitly while configuring the build. This provides a simple way to filter incoming data. PostgreSQL 12 … The specific colors used can be adjusted by setting the environment variable PG_COLORS, using ANSI escape codes for colors. Columns can still be explicitly declared as type oid. this form Allow the BY VALUE clause in XMLEXISTS and XMLTABLE (Chapman Flack). Specifically, dynamic_shared_memory_type can no longer be set to none. The options are --skip-locked and --disable-page-skipping. PostgreSQL 12, the latest version Duplicate index entries are now sorted in heap-storage order. It is only supported if PostgreSQL is compiled with OpenLDAP. Authentication: There is both client and server-side encryption for authentication over GSSAPI (Generic Security Service … In previous releases, Windows builds always printed three digits. ), Treat object-name columns in the information_schema views as being of type name, not varchar (Tom Lane), Per the SQL standard, object-name columns in the information_schema views are declared as being of domain type sql_identifier. Add progress reporting to pg_checksums (Michael Banck, Bernd Helmle). A dump/restore using pg_dumpall or use of pg_upgrade or logical replication is required for those wishing to migrate data from any previous release. Copyright © 1996-2020 The PostgreSQL Global Development Group, PostgreSQL 13.1, 12.5, 11.10, 10.15, 9.6.20, & 9.5.24 Released. Operations on tables that have columns created using WITH OIDS will need adjustment. (Setting allow_system_table_mods is still required. In PostgreSQL, the underlying catalog columns are really of type name. PostgreSQL. Enhancements to administrative functionality, including: REINDEX CONCURRENTLY can rebuild an index without blocking writes to its table, pg_checksums can enable/disable page checksums (used for detecting data corruption) in an offline cluster, Progress reporting statistics for CREATE INDEX, REINDEX, CLUSTER, VACUUM FULL, and pg_checksums, Nondeterministic ICU collations, enabling case-insensitive and accent-insensitive grouping and ordering, Encryption of TCP/IP connections when using GSSAPI authentication, Discovery of LDAP servers using DNS SRV records, Multi-factor authentication, using the clientcert=verify-full option combined with an additional authentication method in pg_hba.conf. These changes primarily improve the efficiency of self-joins on ctid columns. Allow ALTER TABLE ... SET DATA TYPE changing between timestamp and timestamptz to avoid a table rewrite when the session time zone is UTC (Noah Misch). This reduces the number of system calls required for I/O. defined in the SQL/JSON standard. This improves optimization for queries that test several columns, requiring an estimate of the combined effect of several WHERE clauses. For releases before PostgreSQL version 10.0, version numbers consist of three numbers, for example, 9.5.3. This change supports hiding potentially-sensitive statistics data from unprivileged users. This could lead to more accurate, but slightly different, results compared to previous releases. PostgreSQL 12.0 is available.
