I went ahead and pushed Sasaki-san's patch. I think anything we might
do in ecpg is probably just cosmetic and wouldn't get back-patched.

Interesting. This is unhappy about the space before a parameter name,
not the space after a parameter value, so it's a different issue.
But it's weird that ecpg takes it while libpq doesn't. Could libecpg
be modifying/reassembling the URI string? I didn't look.
