# E.152. Release 7.2.5

> Release date: 2004-08-16

This release contains a variety of fixes from 7.2.4.

## E.152.1. Migration to Version 7.2.5

A dump/restore is not required for those running 7.2.X.

## E.152.2. Changes

- Prevent possible loss of committed transactions during crash

  Due to insufficient interlocking between transaction commit and checkpointing, it was possible for transactions committed just before the most recent checkpoint to be lost, in whole or in part, following a database crash and restart. This is a serious bug that has existed since PostgreSQL 7.1.

- Fix corner case for btree search in parallel with first root page split

- Fix buffer overrun in `to_ascii` (Guido Notari)

- Fix core dump in deadlock detection on machines where char is unsigned

- Fix failure to respond to `pg_ctl stop -m fast` after Async_NotifyHandler runs

- Repair memory leaks in pg_dump

- Avoid conflict with system definition of `isblank()` function or macro
