There can be an alternate regression result file to cater that with name suffix _1, e.g. see https://github.com/reorg/pg_repack/tree/master/regress/expected. Could you provide one in a MR please? I swear I'll apply it in a non distant future...

[df7cb]

Will do! (But not now...)

Submitted as #15.

Fixed with #15
