Request to Remove Unused xmin Column from Function Properties Queries

Dear pgAdmin Team,

Queries for the xmin system column are causing errors and breaking
function/property dialogs. I see xmin is fetched in property queries
(e.g., functions/templates/*/properties.sql) but is always ignored in
processing, as in:

web/pgadmin/browser/server_groups/servers/databases/schemas/functions/init.py:
keys_to_ignore = ['oid', 'proowner', 'typnsp', 'xmin', …]

Can we drop xmin from these queries? Are there reasons to keep it? If
not, would you accept a patch to remove it?

Thanks,
Abhinav Patni
