Hi ,
I am working on project which include merging of two databases within
postgresql on Linux. I have searched for s/w but didnt get any useful.
So if any one having any information about such s/w please help me out.
This s/w should have GPL. (Opensource s/w). I want to sync two database
i.e. the s/w should merge the databses insuch a way that they sholud
have same tables and also same records in table. It should generate
script using which I can sync two databases.
Why don't you use Slony or some similar replication solution for Postgres?
They are mode precisely for that.
If you can't (or don't want to) use replication, you might want to have a look at my SQL Workbench/J.
It offers two commands that could do what you want:
WbSchemaDiff[1] which generates an XML description of the schema differences (which can then be transformed into a SQL script)
WbDataDiff[2] can compare the contents (data) of two databases and either run the necessary UPDATE/DELETE/INSERT statements directly or write them as SQL scripts. Especially generating the DELETE
