The Windows parameters for configuring PostgreSQL server are located in two configuration files. A few parameters in these files have to be adjusted before the server can be used in production. Pg_hba.conf a.k.a. PostgreSQL Client Authentication Configuration File The purpose for this file is to identify all of the machines that are able to access PostgreSQL remotely. This is a direct quote from the comments section of the file. “If you want to allow non-local connections, you need to add more “host” records. Also, remember TCP/IP connections are only enabled if you enable “tcpip_socket” in postgresql.conf.” 47. The arguments required are:Type = local or host Database = all or can specify one User = all or can specify one IP-ADDRESS = machines ip address IP-MASK = 255.255.255.0 METHOD = trust This information must be entered for all machines and or users wanting to access PostgreSQL . Postgresql.conf a.k.a. PostgreSQL Configuration File In this file the following must be uncommented in order for remote connections to work.
1. Connection Parameters
2. tcpip_socket = false (default)
tcpip_socket = true port = 5432 There are other settings that need to be dealt with for optimization purposes, but for connectivity purposes only these changes are required.
1. Misc
2. autocommit = true
autocommit = false From PostgreSQL 7.3 Documentation Chapter 10 Performance Tips 10.4.1. Disable Autocommit Turn off autocommit and just do one commit at the end. (In plain SQL, this means issuing BEGIN at the start and COMMIT at the end. Some client libraries may do this behind your back, in which case you need to make sure the library does it when you want it done.) If you allow each insertion to be committed separately, PostgreSQL is doing a lot of work for each record added.
