PostgreSQL xmloption setting How long does changing PostgreSQL's xmloption setting to DOCUMENT from its default CONTENT last? It seems to be DB wide, not Cluster wide (any way to set it on a column by column basis?)

It seems to be connection specific, which is annoying cause I have a SQL script that needs to have it set to DOCUMENT to pass validation. The script is 24GB uncompressed, so I don't feel like modifying it manually.
it is connection specific,

All plain set commands are. (see the set command in sql refernce)

You can make the setting persistent using.

ALTER[user|database] name SET xmloption TO DOCUMENT ;

see the ALTER command in sql reference

Alternatively you can prepare the session or prepend to the stream being sent to psql, you don't need to edit the actual disk file.

In the following examples everything upto the $ represents the prompt,

Using the psql command-line:

  database-$ SET xmloption TO DOCUMENT ;
  database-$ \i filename 


Or the system commmand-line

~$ psql "conmnection-parameters" -c "SET xmloption TO DOCUMENT" -f "filename"
