Support

PostGIS is an open-source project, and support is available from a number of sources.

Reporting Problems

Bugs are reported and managed in a ticket tracker. Please follow these steps:

1. Search the tickets to see if your problem has already been reported. If so, add any extra context you might have found, or at least indicate that you too are having the problem. This will help us prioritize common issues.
2. If your problem is unreported, create a new ticket for it. (If you don’t already have one, you’ll need an OSGeo user ID to create a ticket.)
3. In your report include explicit instructions to replicate your issue. The best tickets include the exact SQL necessary to replicate a problem. Eg. “Run this SQL and the back-end crashes.” or “Run this SQL and the answer is (a), but it should be (b).”
4. If you can test older versions of PostGIS for your problem, please do. On your ticket, note the earliest version the problem appears.
5. For the versions where you can replicate the problem, note the operating system, and the output of the SQL

SELECT version() || ' '
     || postgis_full_version();

Please, do not use the ticket tracker to ask for help, use the users mailing list for that.

Security Reporting

If you believe you have found a security issue, please send an email to security@postgis.net. Follow directions as noted in Security policies and procedures.
