Thread: pgsql: Revert most of 39b66a91bd

Revert most of 39b66a91bd

Reverts most of commit 39b66a91bd, which was found to cause significant
regression for REFRESH MATERIALIZED VIEW. This means only rows inserted
by heap_multi_insert will benefit from the optimization, implemented in
commit 7db0cd2145.
