Forum OpenACS Improvement Proposals (TIPs): TIPs #147, 148 and 149: remove openacs dependence on backwards-compatible settings in postgresql.conf
TIP #147: alter openacs so it doesn't need to have missing from clauses supplied. Reasoning: this option is gone in pg9.
TIP #148: alter openacs so it uses "advanced" flavor regexps rather than "extended", OR find out how to set extended flavor in each individual regexp. Reasoning: this option is gone in pg9.
TIP #149: alter openacs so it no longer depends on oids. Reasoning: While removal of this option may have been forgotten for pg-9.0.0, an email has been sent to postgres-hackers mailing list reminding them to remove this option.
