I propse attached mode file for PostgreSQL. It is an update on the created according to request 301 reflecting version 10.1 of PostgreSQL. It also contains queries to the catalog of the database to get a much simpler access to a good deal of the keywords.
I am not sure whether it make sense to have modes for the various versions of the database. I assume (and feel to be true with respect to 10.1 compared to 9.2) that keywords and of more recent versions are supersets of previous versions.
Sorry, the attached file is broken a bit. The function list contains only a small subset (what was fetched in the first fetch of dbeaver). I will cough up another one, but also including modules.
Diff:
improved file attached
Diff:
Another version where I put RETURN to the others category even though it is not a PostgreSQL keyword.
