Just my 0.02, but I would consider EnterpriseDB if:
1. You need contract support for PostgreSQL whether due to technical
needs that extend beyond what the mailing lists can provide or because
there are organizational requirements to have such support on-call.
2. You need some of the features that EnterpriseDB adds to PostgreSQL -
especially Oracle compatibility.
3. You find compelling added features in EnterpriseDB.
If you use some of the added features in the EnterpriseDB variants you
might find it more difficult to switch to vanilla PostgreSQL. If you
start with vanilla PostgreSQL and then decide you want to move to
EnterpriseDB, I doubt you will encounter much trouble.
Any project or company *can* disappear or get discontinued. For
open-source projects this can happen when the developers drift away or
are all employed by a single company which falls on hard-times.
PostgreSQL shines in this area because the core-developers are scattered
around the world and employed by a diverse group of companies including
EnterpriseDB who have vested interests in ensuring PostgreSQL's viability.
Cheers,
