Hi,

So, how about features in postgesql which exists in oracle db (order is
casual) ?
1. Sequences
2. Packages
3. Functions/procedures
4. Full-text
5. Triggers
6. Jobs
7. Synonyms
8. Replication

1) Serial, but I don't know the Oracle one...
2) Schema ?
3) Yes, functions
4) tsearch2
5) Yes
6) ??
7) ??
8) A couple of solutions

Bit more info (from my own findings migrating from Oracle -> Postgres)

Sequences - YES
Packages - NO (concept doesn't exist in PG)
Functions - YES, Procedures - NO (also no INOUT or OUT parameters)
Full-text - YES, tSearch2
Triggers - YES
Jobs - NO, (but scheduled tasks can be implemented in other ways)
Synonyms - NO (can be frigged using search_paths and schemas)
Replication - more than one option depending on requirement

You will miss certain Oracle features, but once you get into the swing
of postgres you'll not look back. Also consider how much money you'll
save in license fees!

you care nothing about that does it, too.

Amen to that. I have to use Oracle at work, but I use PostgreSQL for
all my side stuff. Man do I ever miss psql when I'm in SQL*Plus...

the size of the frigging download is enough to honk nearly
anyone off.

the thing is what, two orders of magnitude bigger than all of
PostgreSQL?

You can create a schema to put all your functions/procedures in it and provide
access control to it.

I think it is good enough emulation of packages barring compiling them to detect
errors in pl/sql code.

This has been mentioned before and few people reported it to be good enough
workaround..

There is a project on gborg (or maybe pgfoundry) called pgjobs which
aims to create an oracle like task schedular in postgresql. not sure how
mature it is but might be worth a look for those interested in this.

Main features which Oracle have and postgresql no (for me):
- object dependency - when I change any object (view, function ..) in postgresql I have to delete all dependencies
objects - Oracle auto compile all dependencies
- distributed databases - all dml, ddl, connect etc work in distributed systems
- true cursor managment - all oracle command are cursor (parse, bind, fetch arbitary numebr of rows)
- select out of transaction managment (select withoout mutable functions - don't update in database)

Might want to check the postgresql documentation. ;-)
