I am migrating my server application from the existing system to another system. Unfortunately, the existing system is also the database server. It has data stored. Is it possible to copy this data to the other system? I have a copy of all the table schemas.
I have no idea on how to proceed. I am using PostgreSQL.

You could dump the database using
pg_dumpand then restore it on the new server using psql. Here's a couple of commands from the above link:Create the backup:
pg_dump mydb > db.sqlCopy
db.sqlto the new server (specific command depends on OS)Go to the new server
createdb mydb -E UTF8(you don't have to specify UTF8 encoding, but I always do)Then:
psql -d mydb -f db.sqlAs I was answering, JohnP just answered with a fine answer but assumes that
pg_hba.confhas been edited to allow remote connections andpostgres.confhas been edited to listen on the network.
