History
Tomas Vondra fac1b470a9 Disallow SRFs when considering sorts below Gather Merge 
While we do allow SRFs in ORDER BY, scan/join processing should not
consider such cases - such sorts should only happen via final Sort atop
a ProjectSet. So make sure we don't try adding such sorts below Gather
Merge, just like we do for expressions that are volatile and/or not
parallel safe.

Backpatch to PostgreSQL 13, where this code was introduced as part of
the Incremental Sort patch.
