how to get more information from a failed 'sqitch check'

[Greg Hennessy]

I'm a newbie with sqitch, I've created a test area to play with.

My sqitch plan is pretty basic:

(astroconda) [ariel:0 sqitch-test]$ cat sqitch.conf
[core]
        engine = pg
        # plan_file = sqitch.plan
        # top_dir = .
 [engine "pg"]
        target = db:pg://oberon.xxx.xxx/sqitch-test
        # registry = sqitch
        # client = psql
[target "production"]
        uri = db:pg://titania.xxx.xxx/sqitch-test

(astroconda) [ariel:0 sqitch-test]$

A sqitch verify shows I'm ok:

(astroconda) [ariel:0 sqitch-test]$ sqitch verify
Verifying db:pg://oberon.xxx.xxx/sqitch-test
  * q3c .. ok
Verify successful
(astroconda) [ariel:0 sqitch-test]$

but a sqitch check shows an error. However I'm not sure how I find out more information about what error I have. The manual doesn't seem to indicate how to get more information.

(astroconda) [ariel:0 sqitch-test]$ sqitch check
Checking db:pg://oberon.xxx.xxx/sqitch-test
Script signatures diverge at change q3c
Failed one check
(astroconda) [ariel:0 sqitch-test]$

This is admittedly only practice setup, but I'd like to figure out how to properly debug what I've done wrong that sqitch check shows an failed check. Any suggestions?
