postgres is the PostgreSQL database server. In order for aclient application to access a database it connects (over a networkor locally) to a running postgresinstance. The postgres instance thenstarts a separate server process to handle the connection.
One postgres instance always managesthe data of exactly one database cluster. A database cluster is acollection of databases that is stored at a common file systemlocation (the 'data area'). More thanone postgres instance can run on a systemat one time, so long as they use different data areas and differentcommunication ports (see below). When postgres starts it needs to know the location of thedata area. The location must be specified by the -D option or the PGDATAenvironment variable; there is no default. Typically, -D or PGDATA points directlyto the data area directory created by initdb. Other possible file layouts arediscussed in Section18.2.
By default postgres starts in theforeground and prints log messages to the standard error stream. Inpractical applications postgres should bestarted as a background process, perhaps at boot time.
PostgreSQL supports automatic character set conversion between server and client for many combinations of character sets (Section 23.3.4 shows which ones). To enable automatic character set conversion, you have to tell PostgreSQL the character set (encoding) you would like to use in the client. There are several ways to accomplish this. As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion.
The postgres command can also be calledin single-user mode. The primary use for this mode is duringbootstrapping by initdb. Sometimes itis used for debugging or disaster recovery; note that running asingle-user server is not truly suitable for debugging the server,since no realistic interprocess communication and locking willhappen. When invoked in single-user mode from the shell, the usercan enter queries and the results will be printed to the screen,but in a form that is more useful for developers than end users. Inthe single-user mode, the session user will be set to the user withID 1, and implicit superuser powers are granted to this user. Thisuser does not actually have to exist, so the single-user mode canbe used to manually recover from certain kinds of accidental damageto the system catalogs.
Interactive installer by EDB
Download the installer certified by EDB for all supported PostgreSQL versions.
This installer includes the PostgreSQL server, pgAdmin; a graphical tool for managing and developingyour databases, and StackBuilder; a package manager that can be used to download and installadditional PostgreSQL tools and drivers. Blocs 3 1 18. Stackbuilder includes management,integration, migration, replication, geospatial, connectors and other tools.
This installer can run in graphical or silent install modes.
The installer is designed to be a straightforward, fast way to get up and running withPostgreSQL on Windows.
Advanced users can also download azip archiveof the binaries, without the installer.This download is intended for users who wish to include PostgreSQL as part of another application installer.
