| Hi, My PostgreSQL is 9.2.1 in Ubuntu 12.04, I need to set up a connection pool by using pgbouncer. I used "apt-get install pgbouncer", after configuring it, I can now connect to pgbouncer and can use all pgbouncer SHOW commands, however: Q1) Is version "1.4.2/bouncer" the right one for PostgreSQL 9.2? $ psql -U postgres -p 6543 pgbouncer psql.bin (9.2.1, server 1.4.2/bouncer) WARNING: psql.bin version 9.2, server version 1.4. Some psql features might not work. Type "help" for help. No entry for terminal type "xterm-color"; using dumb terminal settings. Q2) if I try the general psql commands, I got errors for example: $ psql -U postgres -p 6543 pgbouncer pgbouncer=# \l ERROR: invalid command 'SELECT d.datname as "Name", pg_catalog.pg_get_userbyid(d.datdba) as "Owner", pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding", pg_catalog.array_to_string(d.datacl, '\n') AS "Access privileges" FROM pg_catalog.pg_database d ORDER BY 1;', use SHOW HELP; Q3) I can connect to pgbouncer by using "psql -U postgres -p 6543 pgbouncer", however if I try to use "-d postgres", I got error: $ psql -U postgres -p 6543 pgbouncer -d postgres psql.bin: warning: extra command-line argument "pgbouncer" ignored psql.bin: ERROR: no working server connection Q4) Which port should I use in my application in order to connect to PostgreSQL via pgbouncer, port 6543 or port 5432? the port value in pgbounce.ini: postgres = port=5432 dbname=postgres listen_port = 6543 the port value in postgresql.conf: port=5432 Please help! Thanks |
