Tom Lane	2594cf0e8c	Revise the API for GUC variable assign hooks. The previous functions of assign hooks are now split between check hooks and assign hooks, where the former can fail but the latter shouldn't. Aside from being conceptually clearer, this approach exposes the "canonicalized" form of the variable value to guc.c without having to do an actual assignment. And that lets us fix the problem recently noted by Bernd Helmle that the auto-tune patch for wal_buffers resulted in bogus log messages about "parameter "wal_buffers" cannot be changed without restarting the server". There may be some speed advantage too, because this design lets hook functions avoid re-parsing variable values when restoring a previous state after a rollback (they can store a pre-parsed representation of the value instead). This patch also resolves a longstanding annoyance about custom error messages from variable assign hooks: they should modify, not appear separately from, guc.c's own message about "invalid parameter value".	14 years ago

Robert Haas	968bc6fac9	sepgsql, an SE-Linux integration for PostgreSQL This is still pretty rough - among other things, the documentation needs work, and the messages need a visit from the style police - but this gets the basic framework in place. KaiGai Kohei	15 years ago
