I did a few tests with ECPG. I'm satisfied with the current behavior, but someone says different. I'd like to share the result. The following literal connection strings succeeded. host1 is a server where PostgreSQL is not running, and host2 is where it's running. I could connect to the database server on host2. EXEC SQL CONNECT TO 'tcp:postgresql://host1,host2:5450/postgres'; EXEC SQL CONNECT TO 'tcp:postgresql://host1,host2:5450,5450/postgres'; EXEC SQL CONNECT TO 'postgres@host1,host2:5450'; EXEC SQL CONNECT TO 'postgres@host1,host2:5450,5450'; EXEC SQL CONNECT TO 'tcp:postgresql://?service=my_service'; ~/.pg_service.conf [my_service] host=host1,host2 port=5450 # and port=5450,5450 case dbname=postgres But this one makes PQconnectdbParams() fail, because the passed "host" is "host1:5450,host2" and "port" is "5450". ECPGconnect()'s parser is different from libpq's. However, the tcp:postgresql:// syntax is not described a URL in the manual, so I think it's sufficient to just describe the syntax in the ECPG article. EXEC SQL CONNECT TO 'tcp:postgresql://host1:5450,host2:5450/postgres'; And without the single quote like below, ecpg fails to precompile the source file. I also think it's enough to state in the manual "quote the connection target if you specify multiple hosts or ports". EXEC SQL CONNECT TO tcp:postgresql://host1,host2:5450,5450/postgres; connect.ec:12: ERROR: syntax error at or near "," Comments?
