pgsql: Use unaligned output in another regression test query to reduce

Use unaligned output in another regression test query to reduce diff noise.

Use the unaligned/no rowcount output mode in a regression tests that
shows all built-in leakproof functions. Currently a new leakproof
function will often change the alignment of all existing functions,
making it hard to see the actual difference and creating unnecessary
patch conflicts.

Noticed while looking over a patch introducing new leakproof functions.
