[FW][FIX] odoo: improve pg_xact error mitigation

Initial PR: #194141

It seems the fix above was not enough as it was assumed that connection (or backend in pg terms) were NOT being reused when initiated through sql_db.connect.

For proper cleanup we need to reach this part of the code which can be done in 3 ways:
- calling UNLISTEN * and committing
- closing the connection
- aborting the transaction (before committing the listen)

UNLISTEN * is a good candidate for this, but closing the connection seems to be the safer option.
