[GENERAL] Any experiences with using PhpUnit's DbUnit extension with Postgres?

Hi all Just wondering if anyone has come across a function which can identify typical user-inputted placeholder values? English language is my scope so typical examples would be "not applicable", "n/a", "na", "none", "--", etc. I know it would be trivial to create but no sense in reinventing

I believe the library is spawning a new connection for each query so that makes perfect sense. I will see what improvements can be made at the application layer and look at using pgbouncer if required =) Thank you for sharing your knowledge! -- Sent via pgsql-general mailing list
