This removal done in the regression tests was not intentional.
I have done some reordering of the code around the new meta-command so
as things are ordered alphabetically, and applied the result.

I like the simplicity of what you are doing here, relying on
PSQL_SEND_QUERY being the default so as we use PQsendQueryParams()
with no parameters rather than PQsendQuery() when the pipeline mode is
not off.
How about adding a check on PIPELINE_COMMAND_COUNT when sending a
query through this path? Should we check for more scenarios with
syncs and flushes as well when sending these queries?
