RE: EnterpriseDB as an Oracle replacement

What version did you eval?

8.2 made huge strides in the right direction and 8.3 will go further towards improving the "compatibility" and inclusion of more coolness.

The EDB partitioning model is closer in comparison to the old school partition views with check constraints model we used to have to employ under Oracle 7.se the right direction and 8.3 will

We evaluated it a few months ago and found that the compatibility was not great in several areas. In the case of PL/SQL stored procedures, for example, they lacked support even for the most basic things that we were looking for, such as:  

• They defaulted to INVOKERS rights (Oracle defaults to DEFINERS)
• They didn't support DEFINERS rights on packages or procedures (functions, yes!?)
• They didn't throw any errors on any stored procedures that couldn't compile when "migrated" to EnterpriseDB
• There's was no status indicator that tells you that the code is even broken (short of trying to run it and finding out the hard way).
• They claimed to have some compatibility with Oracle packages, but the only thing they supported was DBMS_OUTPUT

Obviously this isn't the full and comprehensive list and, perhaps, you don't care about PL/SQL compatibility, but if you have other areas you are concerned about, shoot me an e-mail and I'll try to share what I can.

I know many people have mentioned in the past that they find Postgres a

viable alternative to Oracle for many uses. Now there is EnterpriseDb which

is based on Postgres but takes it one step further and claims it is Oracle

compatible. It even has range partitioning w/o the extra $$$. They are

touting FTD, Vonage and Sony's gaming division as major users.  

Is anyone using EnterpriseDB for there non-critical databases to save money

on licensing? If you are, how accurate are the compatibility claims? I know

it doesn't support XMLTYPE and private synonyms for instance. Anyone done

any benchmarks?
