Question: More complex migrations

[gflarity]

Thanks for the this module, use it all the time and it's always been very reliable.

Question:

I find myself wanting access to the actual Postgres driver from within a migration transaction. This is to programatically select specific values to be inserted into a new column I'm adding before setting it not null. Is there a cannonical way to do this or should just create a multiple step migration and run my own script in between?

Here's a high level overview of what I'm trying to do:

• create a column
• perform somewhat complex logic to populate a column correctly (in node.js not pure sql)
• make that column not null

Thanks,
GF

also runSql already delivers all functionality needed
