TL;DR: Listing PostgreSQL users is straightforward with psql, pgAdmin, and catalog queries, but the real security issue is whether teams can actually see roles, privileges, and session activity well enough to audit access and spot misuse, according to StrongDM. The operational gap is governance, not syntax: access visibility only matters when it is tied to review, logging, and revocation decisions.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “How To List Users in PostgreSQL (psql command & GUI tools)”.
By the numbers:
- Up to 80% of data breaches in the U.S. start with unauthorized access.
Key questions
Q: What breaks when PostgreSQL access reviews focus only on usernames?
A: Usernames do not show inherited privileges, database grants, schema rights, or foreign server access, so a review can appear complete while the real access surface remains broad.
Q: Why does PostgreSQL role membership increase audit and governance risk?
A: Role membership can silently expand a user’s permissions through inheritance, group grants, and object ownership, which makes the visible account list a poor proxy for real access.
Q: How can teams tell whether PostgreSQL access review is actually working?
A: Access review is working when catalog data, membership paths, and session logs line up with approved access and recent business need.
Practitioner guidance
- Map effective PostgreSQL access paths Inventory roles, memberships, schema grants, database ACLs, and foreign server mappings together so you can see who can actually reach data, not just who can log in.
- Tie role review to session evidence Use connection logs, disconnection logs, DDL logging, and pgAudit output to validate whether assigned privileges are being used as expected.
- Revoke stale login-capable roles Remove login privileges and inherited memberships from accounts that no longer need database access, then confirm the change with a fresh catalog query.
Bottom line: PostgreSQL access listing helps only when it is tied to review, logging, and revocation, because visibility alone does not close the governance gap.

PostgreSQL role visibility is not the control; it is the evidence source. The article shows that users, roles, memberships, and privileges can be listed through built-in catalog views and GUI tools. That visibility is useful only when it is attached to a governance process that can review, challenge, and revoke access. The practitioner lesson is that an accessible role inventory is necessary, but not sufficient, for database security.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should database teams treat PostgreSQL user management as part of IAM or as a separate admin task?
A: It should be treated as part of IAM and privilege governance, because PostgreSQL roles are identities with lifecycle, assignment, review, and removal requirements. Keeping it separate usually means stale access, weak revocation discipline, and poor audit evidence. Database admin tasks become safer when they follow the same governance model as other privileged identities.
