Are we talking we about error handling in psql lexer?

What I know, in psql there are no any escaping function now. Yes,
exit(1) is maybe too hard - but it is safe. I didn't write
PQescapeStringConn function, and I am not able to speak, we can ignore
this error result. Full handling of this possible error, means to add
some CHECK over any lexer call.
