It looks good to me:-).

I think rule `connection_target` must be fixed.
Either port or unix_socket_directory can be accepted now(I followed the comment),
but we should discuss about it.
According to the doc, libpq's connection-URI accept both.
The attached patch contains all fixes, and pass test in my environment.
And the following line:
EXEC SQL CONNECT TO unix:postgresql://localhost:/a:/postgres;
is precompiled to:
{ ECPGconnect(__LINE__, 0, "unix:postgresql://localhost:/a:/postgres" , NULL, NULL , NULL, 0); }
Is it OK?
