syscat.py scripts were both modified. pg.py uses it to cache a list of
pks (which is seemingly does for every db connection) and various
attributes. syscat uses it to walk the list of system tables and
queries the various attributes from these tables.
In both cases, it seemingly makes sense to apply what you've requested.

Fix some quoting functions. In particular handle NULLs better.
Use a method to add primary key information rather than direct
manipulation of the class structures.
Break decimal out in _quote (in pg.py) and treat it as float.
Treat timestamp like date for quoting purposes.
Remove a redundant SELECT from the get method speeding it, and
insert since it calls get, up a little.
Add test for BOOL type in typecast method to pgdbTypeCache class.
