Yes. For one of our application that makes massive use of triggers the 
transition from 7.2 to 7.3 was less painful than 7.4 to 8.0. Many of the 
triggers were written with the assumption that foreign key checks were 
effectively delayed until the end of the calling statement.

Just another opinion. Nevertheless if it's feasible to support 7.4 for a 
while, I would recommend it. Also from a marketing statepoint -- having 
back branches supported for a visible amount of time increases people's 
confident in PostgreSQL and it's stability.
