Hello all
I want to copy the data from one table to other table. These tables reside in two different databases.
I am thinking of using following query
insert into table2 (select * from table1)
but the problem is how can I specify the database name?
thanks for the help

Thanks folks!
Following command worked for me
psql -h x.x.x.x -U postgres -d securez -c " copy alerts to stdout " |
psql -h x.x.x.x -U postgres -d p -c " copy alerts from stdin "
but
psql -h x.x.x.x -U postgres -d securez -c " copy (select * from alerts)
to stdout " | psql -h x.x.x.x -U postgres -d p -c " copy alerts from
stdin "
is giving me syntax error as
ERROR: syntax error at or near "("
LINE 1: copy (select * from alerts) to stdout
Any idea ?

you can't
you can do this however:
psql -c " copy (select * from table1) to stdout " database1 | psql -c "
copy table2 from stdin " database2

That syntax needs version 8.3, I usually do it that way, but with a where
clause in the select as most times I don't want the whole table.
