Both Debian squeeze and the PostgreSQL version it ships with (8.4) were discontinued in Summer 2014. To support squeeze-lts, credativ GmbH has maintained a LTS branch of PostgreSQL 8.4, backpatching applicable changes from the next-younger branch (9.0).
So far, three releases have been made on the same day or shortly after the official point releases by the PostgreSQL community. Those releases were then uploaded to squeeze-lts.
This short talk will present the PostgreSQL-LTS effort, which policies were set and what problems we had during the project.
