Hello Tom,
Why not move the printVersion call right after the connection is
created, at line 6374?
I started with that, and one of the 001_pgbench_with_server.pl
tests fell over --- it was expecting no stdout output before a
"Perhaps you need to do initialization" failure. If you don't
mind changing that,
Why would I mind?
I agree that printing immediately after the connection is made is a bit
less astonishing.
Ok, so let's just update the test? Attached a proposal with the version
moved.
Note that if no connections are available, then you do not get the
version, which may be a little bit strange. Attached v3 prints out the
local version in that case. Not sure whether it is worth the effort.
