I created this wiki page:
https://wiki.postgresql.org/wiki/PostgreSQL_vs_SQL_Standard
I'd been thinking of collecting this information for a while, but was
spurred into further action when someone referred me to Markus Winand's
PGCon talk slides.
I think I got all the issues I currently know of, but there may be
more, and others may disagree with my classification of issues or the
rationales for violating the spec. Any feedback?
