commit    ac3dcca22e967ac4a899c4534b4b1c8e807ff71e
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Thu Dec 01 17:44:22 2011 +0000
First released in: 9.2.0, 8.4.10, 9.0.6, 9.1.2

    Fix getTypeIOParam to support type record[].
    
    Since record[] uses array_in, it needs to have its element type passed
    as typioparam.  In HEAD and 9.1, this fix essentially reverts commit
    9bc933b2125a5358722490acbc50889887bf7680, which was a hack that is no
    longer needed since domains don't set their typelem anymore.  Before
    that, adjust the logic so that only domains are excluded from being
    treated like arrays, rather than assuming that only base types should
    be included.  Add a regression test to demonstrate the need for this.
    Per report from Maxim Boguk.
    
    Back-patch to 8.4, where type record[] was added.
