Hi, I have question about connection string of ECPG's CONNECT statement. I'm using postgresql 9.5.17 with ECPG application. When I trying to connect to the database, I found that some characters as password in ECPG's connection_option cannot be accepted. Is the specification of ECPG's connection string (connection_option) different from libpq's one? I referred the below documents. - CONNECT of ecpg: https://www.postgresql.org/docs/9.5/ecpg-sql-connect.html - Connection string of libpq: https://www.postgresql.org/docs/9.5/libpq-connect.html#LIBPQ-CONNSTRING Example: 1. Creating database role with password which contains '&'. > CREATE ROLE myuser LOGIN PASSWORD 'pass&word'; 2. Modifying the pg_hba.conf to use "MD5" as auth-method. 3. pg_ctl reload 4. Connecting from ECPG application with below CONNECT statement. EXEC SQL CONNECT "tcp:postgresql://localhost?user=myuser&password=pass&word"; -> The connection was refused because of password failure. I thought that the '&' should be percent-encoded in connection string. However, it was also failed. EXEC SQL CONNECT "tcp:postgresql://localhost?user=myuser&password=pass%26word"; -> The connection was refused because of password failure. On the other hand, the percent-encoded connection string was able to use in psql. > psql "postgresql://localhost?user=myuser&password=pass%26word" -> I could login as "myuser". So, I think that the connection string specification of ECPG is different from libpq's one. Is there the password character's limitation in ECPG? Regards. -- Yusuke, Egashira
