PostgreSQL has four primary documentation formats:
Plain text, for pre-installation information
HTML, for on-line browsing and reference
PDF or Postscript, for printing
man pages, for quick reference.
Additionally, a number of plain-text README files 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 and Postscript format documentation is available separately for download.
If you see anything in the documentation that is not correct, does not match your experience with the particular feature or requires further clarification, please use this form to report a documentation issue.
