In the publisher, you must create the user with which the subscriber will connect: The role used for the replication connection must have the REPLICATION attribute. This process will create its own temporary replication slot and copy the existing data. Allow time-based server parameters to use units of microseconds ( us) (Tom Lane) Allow fractional input for integer server parameters (Tom Lane) For example, SET work_mem = '30.1GB' is now allowed, even though work_mem is an integer parameter. recovery.signal and standby.signal files are now used to switch into non-primary mode. It is implemented by walsender and apply processes. The walsender process starts logical decoding of the WAL and loads the standard logical decoding plugin. It has the capability to upgrade the PostgreSQL major version without taking extra space and requires a lot less time to upgrade as compared to dump/restore. Some types of joins and index scans are executed in parallel: pg_stat_activity shows the background processes operating on the DB and more information about what's going on.

Here is the command: Here, we can modify the parameter accordingly if the data directory and installation directory, which is not the default one. Make max_wal_senders not count as part of max_connections (Alexander Kukushkin), Add an explicit value of current for recovery_target_timeline (Peter Eisentraut), Make recovery fail if a two-phase transaction status file is corrupt (Michal Paquier). This allows extensions to create planner support functions that can provide function-specific selectivity, cost, and row-count estimates that can depend on the function's arguments. Improve the speed of setting the process title on FreeBSD (Thomas Munro), Allow logging of statements from only a percentage of transactions (Adrien Nayrat). You can insert some test records in your PostgreSQL 11 and validate that you have them in your PostgreSQL 12: At this point, you have everything ready to point your application to your PostgreSQL 12.

I've been running DEV locally on PostgreSQL 11 for months and I know it it works (there are no breaking changes between all of these releases), what version do you have locally? In order to be able to copy the initial data, the role used for the replication connection must have the SELECT privilege on a published table. Include the application_name, if set, in log_connections log messages (Don Seiler), Make the walreceiver set its application name to the cluster name, if set (Peter Eisentraut), Add the timestamp of the last received standby message to pg_stat_replication (Lim Myungkyu), Add a wait event for fsync of WAL segments (Konstantin Knizhnik), Add GSSAPI encryption support (Robbie Harwood, Stephen Frost). be able to upgrade without issues. Follow this formula to compute the new value from the old value: SELECT round(sum(OLD / n::float)) FROM generate_series(1, OLD) s(n); Set the value of effective_io_concurrency returned by the above select statement. As described, In support of this, add hostgssenc and hostnogssenc record types in pg_hba.conf for selecting connections that do or do not use GSSAPI encryption, corresponding to the existing hostssl and hostnossl record types. There may be some other unreported cases Learn how to install PostgreSQL and using Azure Data Studio to work with it. Cause recovery to advance to the latest timeline by default (Peter Eisentraut). # SELECT '1.0.0.0.1'::ltree ~ '*{2}. Allow CREATE TABLE's tablespace specification for a partitioned table to affect the tablespace of its children (David Rowley, lvaro Herrera), Avoid sorting when partitions are already being scanned in the necessary order (David Rowley), ALTER TABLE ATTACH PARTITION is now performed with reduced locking requirements (Robert Haas), Add partition introspection functions (Michal Paquier, lvaro Herrera, Amit Langote).
