Here's what I've come up with to avoid "permission denied" errors when a
RI trigger has to lock a PK table. Whenever the SELECT FOR UPDATE is
executed I temporarily switch the current user id to the owner of the PK
table. It's not the grand unified solution via setuid functions that was
envisioned now and then, but it does the same conceptually. For a
terminally elegant solution I can only suggest not using the SPI
interface.
I recommend this patch to be checked out by someone knowledgeable in the
RI area.
