Hi, If I understand correctly, the problem is that it's not clear which of the 'abc' substrings is matched/returned by the function, right?
I wonder if this is a problem only for understanding the test, or if it makes the tests a bit weaker. I mean, what if the function returns the wrong substring? How would we know? Also, if we tweak this, shouldn't we tweak also the regext_instr() calls a bit earlier in the test script? regards -- Tomas Vondra EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
