A while ago we wrote about DZone RefCards cheatsheets and how its a shame there isn't one for PostgreSQL. They are a very attractive and useful vehicle for learning and brushing up on the most important pieces of a piece of software or framework. Since that time we have been diligently working on one for PostgreSQL to fill the missing PostgreSQL slot. The fruits of our labor are finally out, and a bit quicker than we expected. The cheatsheet covers both old features and new features introduced in PostgreSQL 8.4. We hope its useful to many old and new PostgreSQL users.

PL Python Cheatsheet Overview

PL/Python is the procedural language for PostgreSQL that allows you to write database stored functions and triggers in Python. Python has proved to be a charming language and when used for where it excels, enhances the power of PostgreSQL quite nicely. Unfortunately we can't quite capture all its charm in a single pager cheat sheet, but hopefully this will give you a sense of its usefulness.

Below is a Thumbnail view of the PL\Python cheat sheet. This is by no means comprehensive, but are the features we thought may be useful to know.

PDF Portrait version 8.5 x 11" of this cheatsheet is available at PL/Python Cheatsheet 8.5 x 11 and also available in PDF A4 format and HTML.

PSQL is the command line administration/query tool for PostgreSQL. It is simple, light-weight and packed with a lot of charm. Unfortunately we can't quite capture all its charm in a single pager cheat sheet, but hopefully this will give you a sense of its usefulness.

Below is a Thumbnail view of the PSQL cheat sheet. This is by no means comprehensive, but are the features we use most often. It is also pretty much what you get from the help screen with just some added color.

PDF Portrait version 8.5 x 11" of this cheatsheet is available at PSQL8.3 Cheatsheet 8.5 x 11 and also available in PDF A4 format and HTML.

Hubert has some neat tips for making more effective use of psql

Below is a Thumbnail view of a PostgreSQL 8.3 TSearch Cheat Sheet that covers PostgreSQL 8.3 Full Text search engine constructs.

This one we broke into two pages so its a bit more readable than our PostgreSQL 8.3 cheat sheet.

PDF landscape version 8.5 x 11" of this cheatsheet is available at PostgreSQL 8.3 TSearch Full-Text Search in PDF 8/12 by 11 and also available in PDF A4 format and HTML.

PostgreSQL 8.3 Cheat Sheet Overview

Below is a Thumbnail view of a PostgreSQL 8.3 Cheat Sheet that covers prior PostgreSQL constructs plus new 8.3 features. PDF version of this cheat sheet is available at PostgreSQL 8.3 Cheat sheet in PDF 8/12 by 11", PostgreSQL 8.3 Cheat sheet in PDF A4 and the PostgreSQL 8.3 Cheat sheet in HTML.

We apologize for the small size of the fonts. We tried to keep it to a minimum but had trouble deciding what to leave out to keep it to a one page sheet. So perhaps it would have been better as a 2 part cheatsheet. Anyrate we hope people find it useful.

For people who love cheat sheets, here are two other PostgreSQL cheat sheets on the web which we have found useful and cover slightly different set of things than we do in ours.

Lorenzo Alberton's PostgreSQL cheat sheet - his is similar in structure to ours but for older versions of PostgreSQL and his focus is a little different.
Pete Freitag's PostgreSQL cheat sheet - his is much simpler, but has several useful SQL examples.
