Usage

removeConditionals

Remove checks for the callback being a function. And maybe other conditionals in the future.

client.exec

Send a query that does not include arguments

client.query('select * from users where 42 = id', callback)

client.query

Send a query that does have arguments, in the form of an array

client.query('select * from users where ? = id', [42], callback)
