postinstall script takes 30s on node19+ due to keepalive

[phiresky]

From node 19 (e.g. Node 20, Node 22 LTS), they set keepAlive by default to true. This causes a behaviour (bug?) nodejs/node#47228 where the process also does not exit for 30 seconds.

This can be fixed with this patch

before:
node node_modules/pg-formatter/bin/postinstall-script.js 0,50s user 0,25s system 2% cpu 30,255 total

after:

node node_modules/pg-formatter/bin/postinstall-script.js 0,60s user 0,27s system 61% cpu 1,391 total

patch: (too lazy to make a PR)

This also makes any npm install or yarn install of a package depending on this 30s slower and thus makes our CI 30s slower ;)
