Re: PostgreSQL vs Firebird SQL

I confirm what Josh berkus said. The performance will not be a problem as
soon as you manage your database very well (good configuration, good
hardware, good queries, good data organisation...), like a lot of other
competitors I think?

We have never used Firebird but we use intensively PostgreSQL since 2011 on
thirty servers (independently).
All our servers run an application which have 150 tables, more than 500
handmade queries, where more than 30 % are really complex (more than 2000
lines of code), using a lot of features (json, hstore, full text search,
window functions, custom types, custom window functions, all kind of
indexes, recursive queries, stored procedures, triggers, locks, a lot of
CTEs, range types, arrays types...).
One of our server, which runs Ubuntu Server on a virtualized machine (4
cores, 16 Go RAM), has more than 100 millions of rows with more or less the
same inserts, updates and deletes every day as you.
Hopefully, we've never experienced a data corruption until now ("crossed
fingers").
