commit    7fbbe75875ca510c4fe730c2ecbb48bf54001574
Author:   Nathan Bossart <nathan@postgresql.org>
Date:     Thu Jun 18 16:29:49 2026 +0000
First released in: 14.24, 15.19, 16.15, 17.11, 18.6

    Silence "may be used uninitialized" compiler warning.
    
    Newer gcc warns that this "actual_arg_types" variable may be used
    uninitialized, but visual inspection indicates there's no bug.  To
    silence the warning, initialize the variable to zeros.
