pg-restore

Say I have two host servers s1 and s2. In both the servers i have a schema named n1, now i have made some changes to some of the tables present in schema n1 of s1.

Now my question is ,since there is already the same schema n1 in the server s2 with the same set of tables. what the restore process will do? will it overwrite the existing tables or should i drop the existing schema of server s2 and

I do want to search for some data inside a database dump but these dumps are using the binary-compressed format ( PGDMP header). How can I convert these to SQL without restoring them? Craig Ringer pg_restore , when run without a database name, outputs a text dump to stdout; you can send that elsewhere with -f or with I/O redirection. pg_restore -f mydatabase.sql mydatabase.dump The fastest method that I've used was: pg_restore mybinaryfile.backup > mysqlfile.sql No special flags, since pg_restore just spits it out to stdout.

I just upgraded to postgres 10.2 on mac os which matches 10.2 on heroku. I'm trying to download a copy of the database and restore it locally. Before the upgrade the restore would work fine.

So I regularly backup and restore databases and schema's using pgadmin4. I would like to do it with a batch file using commands as pg_dump and pg_restore. I however always fail to succeed in this and could use some help. The way I try to dump one schema (with data) is the following: pg_dump -U postgres -F c -d database -n schema > mw2 Then I try to restore it with pg_restore: pg_restore -U postgres -d otherdatabase -n schema mw2 First I tried to use .dump in stead of tar but the result stays the same; which is an empty schema in my database. Or the following error message: pg_restore:

I need to dump a postgres database from computer1 with postgres username1 and then restore it on computer2 with postgres username2.
