pgsql: Simplify tab completion rules for views and foreign tables.

Simplify tab completion rules for views and foreign tables.

Since an increasing number of views and foreign tables are now able
to be updated, complete with any table, view, or foreign table in
the relevant contexts. This avoids the need to use a complex
query that may be both confusing to end-users and nonperformant
to construct the list of possible completions.

Dean Rasheed, persuant to a complaint from Bernd Helme and a
suggestion from Peter Eisentraut
