	Hi Peter,

	 

	1)       We are using "psql 7.4.2" version of Postgresql, need
to create a new schema similar to the current schema with all the
objects as in the current schema. Do we have any command to support this
operation?

	2)       We need to shift all the data between 2 different
databases in 2 different servers. What is the best way to go either
backup or copy command? 

	3)       Any equivalent command to export and import commands in
Oracle/SQL.

	 

	Can you please give some knowledge on this 

1:  Upgrade to 7.4.18 (or whatever the latest is) as soon as you can.
Use pg_dump with the -s switch to get just the schema and objects but no
data out.  pg_dump --help will give you a list of all the options that
command has.  To put your new schema into another database, just
redirect that file to psql: 

pg_dump -s -h olddbserver olddbname > schemafile.sql
psql -h newserver newdbname < svhemafile.sql

2: pg_dump is the best way to go.  pg_dumpall can dump everything,
including user accounts from one server.  Then feed the output to psql
or pg_restore. 

3: pg_dump is export, psql or pg_restore are import
