Make PG_TEST_NOCLEAN work for temporary directories in TAP tests

michaelpq · michaelpq · commit c8987ea90cf2 · 2023-07-03T10:06:16.000+09:00
When set, this environment variable was only effective for data directories but not for all the other temporary files created by PostgreSQL::Test::Utils. Keeping the temporary files after a successful run can be useful for debugging purposes. The documentation is updated to reflect the new behavior, with contents available in doc/ since v16 and in src/test/perl/README since v15.
