doc: references to node-pool

[AurelienGasser]

There are a few references to node-pool (https://github.com/coopernurse/node-pool) in the doc and comments, e.g.

node-postgres/packages/pg-pool/README.md

Line 28 in f332f28

// and the node-pool (https://github.com/coopernurse/node-pool) constructor

However, node-pool doesn't seem used in the project anymore. Am I missing something?

You’re right. The most up-to-date documentation is at https://github.com/brianc/node-postgres/tree/master/docs = https://node-postgres.com/; many of the READMEs are out of date.
