ASE is a more modern version of what Microsoft originally used to
create their "enterprise" database product; for better or worse, it's
certainly a mature, scalable database system.
Until version 11, Sybase was strongly criticized for only supporting
page locks, and not row locks. (SAP long refused to port their R/3
application to Sybase for this specific reason, and it was quite a big
deal when Microsoft modified their version to support row locks
BECAUSE OF THIS.)
I expect that reality was that _proper_ Sybase application design
involved pushing updates off to some central "TP manager-like" process
which would make the locking issues disappear, but that is quite a
different design than people _usually_ use, and certainly imposes on
system architecture.
It seems unlikely that Sybase ASE is either _spectacularly_ better or
worse than PostgreSQL, but for those that feel more comfortable with
there being a familiar-sounding company that could be sued, or with
the notion that you'd have to pay money for anything that is worth
anything, ASE would certainly be more "comfortable" than PostgreSQL.
