Attached is the patch I just applied to CVS HEAD to fix the search_path
problem that Olivier Prenant recently identified (can't set a search
path for another database if it mentions schemas not present in the
current database). I am looking for comments on whether to back-patch
this into REL7_4_STABLE. It is a rather large patch to fix what might
be considered a non-critical problem, so I'm a bit hesitant about back
patching. Any opinions?
regards, tom lane

If an assign_hook is provided, it points to a function of the signature
! bool assign_hook(newvalue, bool doit, bool interactive)
! where the type of 'newvalue' matches the kind of variable. This function
is called immediately before actually setting the variable's value (so it
can look at the actual variable to determine the old value). If the
function returns "true" then the assignment is completed; if it returns
"false" then newvalue is considered invalid and the assignment is not
performed. If "doit" is false then the function should simply check
! validity of newvalue and not change any derived state. "interactive" is
! true when we are performing a SET command; in this case it is okay for the
! assign_hook to raise an error via elog(). If the function returns false
! for an interactive assignment then guc.c will report a generic "invalid
! value" error message. (An internal elog() in an assign_hook is only
! needed if you want to generate a specialized error message.) But when
! "interactive" is false we are reading a non-interactive option source,
! such as postgresql.conf. In this case the assign_hook should *not* elog
! but should just return false if it doesn't like the newvalue. (An
! elog(LOG) call would be acceptable if you feel a need for a custom
! complaint in this situation.)
For string variables, the signature for assign hooks is a bit different:
const char *assign_hook(const char *newvalue,
