I would recommend https://github.com/Vonng/pg_exporter for some reasons:

Support both Postgres & Pgbouncer
Flexible: Almost all metrics are defined in customizable configuration files in SQL style.
Fine-grained execution control: Tags Filter, Facts Filter, Version Filter, Timeout, Cache, etc..
Dynamic Planning: you could define multiple branches for a collecto. Queries matches server version & fact & tags will be actually executed.
Configurable caching policy & query timeout
Rich metrics about pg_exporter itself.
Auto discovery multi-database in the same instance
Tested and verified in real world production environment for 3+ years (200+ Nodes)

The most important part is: it has a complete solution for monitoring & dashboards:
