Thread: comments in load scripts

comments in load scripts

From
"Aurangzeb M. Agha"

I have two questions regarding using load scripts to create and populate
my DB.

I use the following command to create my DB with a script which has a lot
of create statements in it:

    %> psql testDB < loadTestDB.sql

Question 1: Is this the best way to create my DB?  I know there's a pg_dump
command, but is there some kind of a pgload I should be using instead?

(I got the above command from "9.1.1 Restoring the Dump" from the Admin
guide.

Secondly, my create and populate scripts are very long.  When running the
populate script, I get a ton of output with Insert OID statements:

    ...
    INSERT 30094 1
    INSERT 30095 1
    INSERT 30096 1
    INSERT 30097 1
    INSERT 30098 1
    ...

Is there any way I can put comments into my load scripts so that I can get
an indication of the progress the load is making.  I'd like to see
something like:

    Populating Users Table
    INSERT 30094 1
    INSERT 30095 1

    Populating Role Table
    INSERT 30096 1
    ...

I'd like this functionality for debugging purposes.  I've looked through
the archives and the docs and not found a possible solution.

    Thx in Advance,
    Aurangzeb

You can put SQL comments in your script:

  -- This is a comment (preceded by a double hyphen)

You can see these comments and the commands being executed by running
psql with the -e option:

      %> psql -e -d testDB < loadTestDB.sql
