RE: Question about password character in ECPG's connection string

Hi, Giuseppe,

Thanks to response to my question!

Yes, I could connect to database with "USER" and "IDENTIFIED BY" phrase in CONNECT statement.
However, I could also connect to database with password in connection string when my password does not contains '&'
character.

1. In database, 
   > CREATE ROLE myuser LOGIN PASSWORD 'password';
2. In ECPG application,
   EXEC SQL CONNECT "tcp:postgresql://localhost?user=myuser&password=password";
     -> The connection was succeeded.

This behavior confuse me. 

If user and password cannot write in connection string, what are parameters allowed in "connection_option" ?
I hope I can get this information from the ECPG documentation.

Regards.
