fmgr.c contains this:
/*
* !!! OLD INTERFACE !!!
*
* fmgr() is the only remaining vestige of the old-style caller support
* functions. It's no longer used anywhere in the Postgres
distribution,
* but we should leave it around for a release or two to ease the
transition
* for user-supplied C functions. OidFunctionCallN() replaces it
for new
* code.
*
* DEPRECATED, DO NOT USE IN NEW CODE
*/
which git tells me dates from:
48165ec2 ( Tom Lane 2000-06-05 07:29:25 +0000 2080)
Should we just drop all support for the old interface now?
cheers
