How can I export the schema of a database in PostgreSQL

Question

My computer broke down but fortunately I backed up  the folder C  Program Files PostgreSQL   Now I m working in a new computer and I would like to import the previous Postgres databases that are stored in the external disk   I would like to export the schema of a specific database that is located in the backup folder   The file PostgreSQL 8 3 data global pg database contains information about databases and their OIDs  for example    db1  20012  db2  23456   I would like to export the schema of  db1    There is a folder named  20012  in folder  PostgreSQL 8 3 data base 20012  that contains a lot of files  500 files    Is there any way to export the schema of that database   Note that all of the Postgresql database files are located  in an external hard disk and I would like to export the schema of that database in an SQL file  take that file  run it and create the same exact database locally

You should use something like this pg dump --schema your schema name db1  for details take a look here

set up a new postgresql server and replace its data folder with the files from your external disk    You will then be able to start that postgresql server up and retrieve the data using pg dump  pg dump -s for the schema-only as mentioned

pg dump -d  lt databasename gt  -h  lt hostname gt  -p  lt port gt  -n  lt schemaname gt  -f  lt location of the dump file gt    Please notice that you have sufficient privilege to access that schema  If you want take backup as specific user add user name in that command preceded by -U

pg dump -s databasename -t tablename -U user -h host -p port  gt  tablename sql this will limit the schema dump to the table  quot tablename quot  of  quot databasename quot

If you only want the create tables  then you can do pg dump -s databasename   awk  RS     CREATE TABLE

You should take a look at pg dump   pg dump -s databasename   Will dump only the schema to stdout as  sql   For windows  you ll probably want to call pg dump exe  I don t have access to a Windows machine but I m pretty sure from memory that s the command  See if the help works for you too

In Linux you can do like this  pg dump -U postgres -s postgres  gt  exportFile dmp   Maybe it can work  in Windows too  if not try the same with pg dump exe   pg dump exe -U postgres -s postgres  gt  exportFile dmp
