feat: additional pg catalog fix from dbeaver queries

[sunng87]

Fixes #190

This patch includes some additional fixes for better dbeaver compatibility:

• Regenerate all arrow feather files to ensure we use int32 for oid, instead of uint32. It seems we missed some tables in our last attempt
• Fixed bug with our table alias rewrite rule to avoid prepending table alias for already aliased identifier
• Added empty implementation of 4 pg_catalog functions
