[Epic] Catalog addtions for Metabase compatablity

[RustomMS]

• Store external table column info #703
• Catalog builtin for pg_type #747

[RustomMS]

Metabase steps:

sync-timezone:

• error in transaction begin
• error running to_char(current_timestamp, 'YYYY-MM-DD HH24:MI:SS.MS TZ')

sync-tables:

• Passes with additional empty catalog builtins

sync-fields:

• Error getting fields for tables synced
• pg_attrdef table required
• pg_get_expr required

We are hitting an error due to a datafusion limitation on a where-in subquery filter clause used by metabase:
apache/datafusion#5633

For this query:

SELECT nspname, typname FROM pg_type t JOIN pg_namespace n ON n.oid = t.typnamespace WHERE t.oid IN (SELECT DISTINCT enumtypid FROM pg_enum e);

Though the result should be empty. Next one requires columns and types to be able to join together so working on a glare_types builtin table and pg_type builtin view
