Re: [PATCH v1] Add \echo_stderr to psql

Hello David,

About v3. Applies, compiles, global & local make check are ok. doc gen ok.

Cannot see it:

   + else if (strcmp(cmd, "echo") == 0 || strcmp(cmd, "warn") == 0 || strcmp(cmd, "qecho") == 0)

I think that putting together the 3 echo variants help makes sense, but 
maybe someone will object about breaking the abc order.
