An extension can already de facto reserve a GUC prefix using EmitWarningsOnPlaceholders(). But this was only checked against settings that exist at the time the extension is loaded (or the extension chooses to call this). No diagnostic is given when a SET command later uses a nonexisting setting with a custom prefix. With this change, EmitWarningsOnPlaceholders() saves the prefixes it reserves in a list, and SET checks when it finds a "placeholder" setting whether it belongs to a reserved prefix and issues a warning in that case. Add a regression test that checks the patch using the "plpgsql" registered prefix.

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
