PostgreSQL | Bugfix releases for 7.2, 7.3 and 7.4
A potential 'data loss' bug and several minor fixes are covered by the latest PostgreSQL "point" releases: 7.2.6, 7.3.8 and 7.4.6 (announcement). Additionally a minor security risk involving the script
make_oidjoins_check's use of temporary files has been fixed.
Source files are available from FTP mirrors, see http://www.postgresql.org/mirrors-ftp.html.
UPDATE: apparently two further, slightly more serious but non-specified security fixes are included in these releases.
