RI triggers would fail for datatypes using old-style equal function,
...
because cached fmgr info contained reference to a shorter-lived data
structure. Also guard against possibility that fmgr_info could fail,
leaving an incomplete entry present in the hash table.

Change SearchSysCache coding conventions so that a reference count is
...
maintained for each cache entry. A cache entry will not be freed until
the matching ReleaseSysCache call has been executed. This eliminates
worries about cache entries getting dropped while still in use. See
my posting to pg-hackers of even date for more info.
