Hi everyone on the list.
I've been trying to get a way to copy a postgresql table or some columns from table into another one, but this new table must be in another databse and, also, could be in another server. I was working on a jdbc app , which run well when the destiny table was in the same database than the source ( it was with "create table as select ... into)"), really easy, but we have the other case.
I feel it could be possible writing a function , which receives some variables ( postgresql server, db and table, sql query for filtering data). The problem is that I cant find any example about the following:
-- connecting to a server within the function.
-- retrieve data form this server ( I think some cursors would be useful to save each column, and run by the rows)
-- connecting to another server, und create a table (with a name provided by user), where I can insert data from cursors.
I think it could be answered by replication (Slony ? ), but I have to do it without any other tool.
Does anyone knows If it's possible, and how to do it?
thanks in advance.
