Are it is good idea to add to PQsetdb parameters
parameter "USER to conect as" ?

Yup. PQsetdb() is deprecated these days --- you should really be
calling PQsetdbLogin() or even better PQconnectdb() instead.

(Or probably there is other way to specify postgres USER, different from
pogram euid?)

If you don't provide a user ID parameter, libpq will look first for
an environment variable PGUSER, and failing that use getpwuid(geteuid())
to find out who you are.
