This commit adds columns in view pg_stat_subscription_stats to show the
number of times a particular conflict type has occurred during the
application of logical replication changes. The following columns are
added:
confl_insert_exists:
Number of times a row insertion violated a NOT DEFERRABLE unique
constraint.
confl_update_origin_differs:
Number of times an update was performed on a row that was
previously modified by another origin.
confl_update_exists:
Number of times that the updated value of a row violates a
NOT DEFERRABLE unique constraint.
confl_update_missing:
Number of times that the tuple to be updated is missing.
confl_delete_origin_differs:
Number of times a delete was performed on a row that was
previously modified by another origin.
confl_delete_missing:
Number of times that the tuple to be deleted is missing.
The update_origin_differs and delete_origin_differs conflicts can be
detected only when track_commit_timestamp is enabled.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check". Check src/test/Makefile to see which tests get run automatically. authentication/ Tests for authentication (but see also below) examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level kerberos/ Tests for Kerberos/GSSAPI authentication and encryption ldap/ Tests for LDAP-based authentication locale/ Sanity checks for locale data, encodings, etc mb/ Tests for multibyte encoding (UTF-8) support modules/ Extensions used only or mainly for test purposes, generally not suitable for installing in production databases perl/ Infrastructure for Perl-based TAP tests recovery/ Test suite for recovery and replication regress/ PostgreSQL's main regression test suite, pg_regress ssl/ Tests to exercise and verify SSL certificate handling subscription/ Tests for logical replication
