This patch causes EXPLAIN output to refer to objects that are in the current session's temp schema with the "pg_temp" schema alias rather than that schema's actual name. This is useful for our own testing purposes since it will stabilize EXPLAIN VERBOSE output for such cases, allowing us to use that in regression tests. It should be less confusing for end users too. Since ruleutils.c needs to change behavior for this, the change also leaks into a few other users of ruleutils.c, for example pg_get_viewdef(). AFAICS that won't cause any problems. We did find that aggressively trying to change this behavior across-the-board would cause issues, but as long as "pg_temp" only appears within generated SQL text, I think it'll be fine. Along the way, make get_namespace_name_or_temp conform to the same API as get_namespace_name, ie that it returns a palloc'd string or NULL. The current behavior hasn't caused any bugs since no callers attempt to pfree the result, but if it gets more widespread usage that could become a problem.

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
