v02-0001-psql-Create-new-sendpipeline-meta-command.patch (application/octet-stream)
v02-0002-psql-Allow-to-add-queries-in-an-ongoing-pipeline.patch (application/octet-stream)

Here is a new patch set:

0001: This introduces the \sendpipeline meta-command and forbid \g in
a pipeline. This is to fix the formatting options of \g that are not
supported in a pipeline.

0002: Allows ';' to send a query using extended protocol when within a
pipeline by using PQsendQueryParams with 0 parameters. It is not
possible to send parameters with extended protocol this way and
everything will be propagated through the query string, similar to a
simple query.
