pgsql: Update SQL features list

Update SQL features list

Feature F692 "Extended collation support" is now also supported. This
refers to allowing the COLLATE clause anywhere in a column or domain
definition instead of just directly after the type.

Also correct the name of the feature in accordance with the latest SQL
standard.
