OK, and which behavior is getting changed, to what? I am not interested
in trying to reverse-engineer a specification from the patch.
My recollection is (and the archives seem to agree) that normal
execution and SQL functions were changed to only advance the CID instead
of taking a new snapshot. EXPLAIN ANALYZE and SPI (not exactly sure
about this one) did that already so they were just changed to use the
new API.
OK, so the intent is that in all cases, we just advance CID and don't
take a new snapshot between queries that were generated (by rule
expansion) from a single original parsetree? But we still take a new
snap between original parsetrees? Works for me.
Exactly.
