Hi,

all along we have been using other RDBMSs in NT
environment and now we are thinking of Linux

But these features we need, Are they available
in PG-SQL

1. Log of transactions than can be disassembled
into SQL and placed on different media for recovery

2. Replication accross mutli-site file-based

3. Specifying a sub-query in place of a column-name
   or in place of a table-name (in the from clause)

Regards

Target list yes, from clause nope.


At least item 1 and 3 are slated to be implemented some time, but that
won't help you very much right now. :(
