Managers want support, they can't live without. Every piece of
software has its flaws and needs patches. PostgreSQL is supported for
5 years, the latest version (8.4) will be supported at least until
2014. In total there are 6 supported version as we speak, 7.4 - 8.4.
MySQL has active support for 5.0 and 5.1 but 5.0 will only be
supported for the next two weeks and 5.1 until december next year.
Unless you pay for an extended support contract. After 5.1 there is no
other stable version at this moment, nobody knows what comes next.

Good luck!

Hi Everyone:
Tomorrow, I will need to present to a group of managers (who know
nothing about DBs) why I chose to use PG over MySQL in a project,
MySQL being the more popular DB choice with other engineers, and
managers fearing things that are “different” (risk). I have a few
hard tecnical reasons (check constraint, deferred constraint
checking, array data type), but I’m looking for a “it’s more
reliable” reasons. Again, the audience is managers. Is there an
impartial, 3rd party evaluation of the 2 DBs out there that
identifies PG as being more reliable? It might mention things like
fewer incidences of corrupt tables/indexes, fewer deamon crashes,
better recovery after system crashes, etc... ?
Thanks !
