When a standby replays an XLOG_PARAMETER_CHANGE record that lowers wal_level below logical, we invalidate all logical slots in hot standby mode. However, if this record was replayed while not in hot standby mode, logical slots could remain valid even after promotion, potentially causing an assertion failure during WAL record decoding. To fix this issue, this commit adds a check for hot_standby status when restoring a logical replication slot on standbys. This check ensures that logical slots are invalidated when they become incompatible due to insufficient wal_level during recovery. Backpatch to v16 where logical decoding on standby was introduced.

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
