Continuing the religious theme, having been raised in a Pentecostal area (SW Missouri), one of the things I like about PostgreSQL is that I haven't felt the desire to lay my hands upon any of my servers and intone, "Lord, HEAL this database. SHOWER your MERCY upon...."

It's comparable to the quality I've enjoyed with Oracle and DB2 on Solaris and Windows in the bad old days, and has all the features I need to declaratively enforce consistency, correctness and referential integrity.
