## E.307. Release 7.3.17

Release date: 2007-01-08

This release contains a variety of fixes from 7.3.16.

### E.307.1. Migration to Version 7.3.17

A dump/restore is not required for those running 7.3.X. However, if you are upgrading from a version earlier than 7.3.13, see Section E.311.

### E.307.2. Changes

- `to_number()` and `to_char(numeric)` are now `STABLE`, not `IMMUTABLE`, for new initdb installs (Tom)

  This is because `lc_numeric` can potentially change the output of these functions.

- Improve index usage of regular expressions that use parentheses (Tom)

  This improves psql `\d` performance also.
