# Wrapper around pg_regress and pg_isolation_regress to be able to control the schedule with environment variables
#
# The following control variables are supported:
#
# TESTS     only run tests from this list
# IGNORES   failure of tests in this list will not lead to test failure
# SKIPS     tests from this list are not run
#
# In TESTS you may use wildcards to match multiple test names
# TESTS="compression*" will match all tests whose name starts with compression
# TESTS="*compression*" will match all tests that have compression anywhere in the name
# Wildcard matching also applies to version specific tests so compression-13
# would also be matched by those patterns.
