E.55. Release 7.3.17

E.55.1. 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 the release notes for 7.3.13.

E.55.2. 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.
