Frequently asked questions ( 5 )

How do I change the sort ordering of textual data in PostgreSQL?

PostgreSQL sorts textual data according to the ordering that is defined by the current locale, which is selected during initdb.

How does PostgreSQL use CPU resources?

The PostgreSQL server is process-based (not threaded). Each database session connects to a single PostgreSQL operating system (OS) process. Multiple sessions are automatically spread across all available CPUs by the OS.

How do I control connections from other hosts on PostgreSQL?

PostgreSQL only allows connections from the local machine using Unix domain sockets or TCP/IP connections. Other machines will not be able to connect unless you modify listen_addresses in the postgresql.conf file, enable host-based authentication by modifying the $PGDATA/pg_hba.conf file, and restart.

Why phpPgAdmin ask me to re-enter login information for every page I access on PostgreSQL?

You most certainly have a problem with your PHP sessions. Make sure:

your browser accept cookies if your session ID relies on them

PHP has write access to the path set in the parameter “session.save_path” of your php.ini

What happened to the database dump feature in phpPgAdmin on PostgreSQL?

You need to configure phpPgAdmin (in the config.inc.php file) to point to the location of the pg_dump and pg_dumpall utilities on your server. Once you have done that, the database export feature will appear.
