Subject: psql: Disable %P (pipeline status) for non-active connection
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d42735b1e8c8c6454a07b709e4ff7ccae4ad58c6;p=thirdparty%2Fpostgresql.git

psql: Disable %P (pipeline status) for non-active connection

In the psql prompt, %P prompt shows the current pipeline status.  Unlike
most of the other options, its status was showing up in the output
generated even if psql was not connected to a database.  This was
confusing, because without a connection a pipeline status makes no
sense.

Like the other options, %P is updated so as its data is now hidden
without an active connection.
