Subject: Use literal_column() instead of literal() in test
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F8707%2Fhead;p=thirdparty%2Fsqlalchemy%2Fsqlalchemy.git

Use literal_column() instead of literal() in test

This is an attempt to workaround an issue with asyncpg, where passing a
literal range as argument causes the following error:

<class 'asyncpg.exceptions.DataError'>: invalid input for query argument $1: 'empty' (list, tuple or Range object expected (got type <class 'str'>))
