Thank you for the report and test case. I modified it a hair 
and added to the repo in the testme.tmp.pl file, and was 
able to verify the leak. I made a small change in commit 
36463bd3e72c0f274488be2cbdde61365335b
that fixes it some - we now only leak 6 SVs per round. I will 
take a closer look when I am fully caffeinated and my mind 
is clear, as XS mortalization is a real bugbear. If anyone 
else wants to take a look, the problem is somewhere in 
pg_destringify_array function inside of dbdimp.c

I verified that the problem is in that block by setting:

$dbh->{pg_expand_array} = 0;

If that is set, no leak is seen in the test case.
