This may be the worst bikeshedding issue report ever, but... The META.json file generated by pgxn-utils currently uses 3-space indent, which is ugly. Is there any reason for this choice?
The PostgreSQL project classically uses 4-char indent, it would be much better to stick with that. There are some projects that use 2 or 8. But 3, srsly, who uses that? :)
Even the pgxn-utils project ITSELF doesn't use 3-space indentation in its META.json.
I'll fix that for next version that will be available until Mar 30.
adjusts tab from 3 to 4 spaces, fix #30
