PostgreSQL has four primary documentation formats:
- Plain text, for pre-installation information
- HTML, for on-line browsing and reference
- PDF, for printing
- man pages, for quick reference.
Additionally, a number of plain-text
READMEfiles can be found throughout the PostgreSQL source tree, documenting various implementation issues.
HTML documentation and man pages are part of a standard distribution and are installed by default. PDF format documentation is available separately for download.
