commit    bb30410b9f4cae1ec74f120833b74ecc0b1de7d2
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Sun Jul 17 21:43:28 2022 +0000

    Fix omissions in support for the "regcollation" type.
    
    The patch that added regcollation doesn't seem to have been too
    thorough about supporting it everywhere that other reg* types
    are supported.  Fix that.  (The find_expr_references omission
    is moderately serious, since it could result in missing expression
    dependencies.  The others are less exciting.)
    
    Noted while fixing bug #17483.  Back-patch to v13 where
    regcollation was added.
