more info in permission errors

Hi All,

I recently had a spate of permission probs on our PHP site, with lots of log
entries like this:

2002-01-31 09:20:58 ERROR: users_stats: Permission denied.
2002-01-31 09:20:58 ERROR: recipe_recipes: Permission denied.

What I would like to see instead is:

2002-01-31 09:20:58 ERROR: Permission denied: INSERT on table "users_stats"
for "au-users".
2002-01-31 09:20:58 ERROR: Permission denied: SELECT on table
"recipe_recipes" for "au-recipes".
2002-01-31 09:20:58 ERROR: Permission denied: UPDATE on sequence "blah" for
"adsfafds".

That would have made my job of tracking down the errors MUCH easier.

I've looked in backend/catalog/aclparse.c (IIRC) but all it has is the
static string 'Permission denied'. Looks like you have to fix every call to
acl_check() Would someone with more postgres experience be able to do up a
patch for it? Or at least add it to the TODO?

I'd _love_ to have this functionality - it would have come in useful many
times in the past...
