pg_stat_statements: Add tests with extended query protocol
There are currently no tests in the tree checking that queries using theextended query protocol are able to map with their query ID.This can be achieved for some paths of the extended query protocol withthe psql meta-commands \bind or \bind_named, so let's add some testsbased on both.I have found that to be a useful addition while working on a differentissue.Discussion:https://postgr.es/m/ZuEt6MOEBSlifBfn@paquier.xyz
