A thinko concerning nesting depth caused json_to_record() to produce bogus output if a field of its input object contained a sub-object with a field name matching one of the requested output column names. Per bug #13996 from Johann Visagie. I added a regression test case based on his example, plus parallel tests for json_to_recordset, jsonb_to_record, jsonb_to_recordset. The latter three do not exhibit the same bug (which suggests that we may be missing some opportunities to share code...) but testing seems like a good idea in any case. Back-patch to 9.4 where these functions were 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. examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level 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 thread/ A thread-safety-testing utility used by configure
