My point was that I didn't think you'd thought about error handling.
In particular, it appears to me that if the strdup in pg_fe_getauthname
fails, we'll just let that pass without comment, which is inconsistent
with all the other out-of-memory cases in conninfo_add_defaults.
(I wonder whether any code downstream of this supposes that we always
have a value for the "user" option. It's a pretty safe bet that the
case is hardly ever tested.)
More generally, why is it that we'd want to eliminate any prospect
of reporting other errors in pg_fe_getauthname? Is it such a great
idea that we're ignoring failure returns from pqGetpwuid/GetUserName?
