You are right, it seems that they were not getting compressed, probably
because the arrays were "seq 10000" which seems to not get compressed by
pglz. When I changed the test data to an array containing 10000 ones, there
were no speed improvement anymore.

I'll look into how to improve the compressed case and other issues you
