Hi,
generic_option_name is a ColLabel, therefore a fully general SQL identifier.
But a command like CREATE FOREIGN DATA WRAPPER w ... OPTIONS ("a=b" 'c=d')
stores {a=b=c=d} in fdwoptions, from which the original intent can't be
recovered.
Should generic_option_name be restricted to be a regular identifier,
or allowed to be a delimited identifier but with = forbidden within it,
or should it be represented as delimited in the catalog when necessary
so it can be recovered faithfully?
SQL rules would also make its case-sensitivity dependent on faithfully
recovering whether it was delimited or not.
