Thread: How to import *.sql file to postgresql database

Hi,

I have a DUMP file with INSERT's commands. I need to import this data to postgresql database with the "psql" command.

How can I do this task?

Best Regards,

From manual [1] 24.1.1. Restoring the dump:
psql dbname < infile

Thanks for the reply,

I have this error:

[quote]
ERROR:  invalid byte sequence for encoding "UTF8": 0xff
HINT:  This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding".
[/quote]

I have set the client encoding to LATIN1 like this,

[quote]
$psql <database>
database=> set client_encoding to "LATIN1";
SET
database=>\i /home/folder1/data.sql
[/quote]

Then I got this different error:

[quote]
psql:/home/folder1/data.sql:1: ERROR:  syntax error at or near "ÿþ"
LINE 1: ÿþ-
        ^
[/quote]

How should I solve this problem?

I think

psql -U user_name database_name <dump_file

EDoardo

If I do this command gives me the same error:

[quote]
ERROR:  invalid byte sequence for encoding "UTF8": 0xff
HINT:  This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding".
[/quote]

What more can I do?

A BOM (Byte Order Mark) case?

You still have an encoding/decoding issue, so your load sequence is not
occurring under a LATIN1 encoding in this instance. You may want to look
at iconv to convert your source to a more desirable encoding.

However, from your emails it may be that your file is not a normal text
file dump, but a dump file made with the -Fc flags. Please read the
pg_dump manpage, and, if after inspection of the file itself it proves
to be in the custom, compressed format produced by -Fc, you should use
the pg_restore command to restore from this file.
