commit    70bfc5ae537c8bfeed4849b7d9f814de89a155fe
Author:   Michael Paquier <michael@paquier.xyz>
Date:     Wed Oct 27 07:02:19 2021 +0000
First released in: 15.0

    Add test for copy of shared dependencies from template database
    
    As 98ec35b has proved, there has never been any coverage in this area of
    the code.  This commit adds a new TAP test with a template database that
    includes a small set of shared dependencies copied to a new database.
    The test is added in createdb, where we have never tested that -T
    generates a query with TEMPLATE, either.
