Hi all. Under Linux I'm trying to communicate to an instance of the psql client running in the background through a couple of named pipes. I'd like to do something like this: $ mkfifo /tmp/pg_ipipe /tmp/pg_opipe $ psql -d testdb -U testuser < /tmp/pg_ipipe > /tmp/pg_opipe & ... $ echo "\t" > /tmp/pg_ipipe $ echo "select count(*) from test_table;" > /tmp/pg_ipipe $ read COUNT < /tmp/pg_opipe The psql client connects to the DB abd waits for the first commad coming from the "pg_ipipe" and executes it. Fine. The problem is that it quits soon after instead of waiting for the second (and any subsequent) command, as we all see in the usual command line usage. I've also tried to add a "--file -" with no luck. It seems that when the psql is getting the input from a named pipe acts as if the "--command" option were active. I'm sure I'm missing something. But don't know what. Is there any hint? MTIA! -- Vincenzo Romano ---- Maybe Computers will never become as intelligent as Humans. For sure they won't ever become so stupid. [VR-1987]
