TL;DR: Creating tables in PostgreSQL depends on correct schema design, constraints, and sequence handling, but production risk comes from who can create, alter, or drop tables and how that access is audited, according to StrongDM. The security issue is not table syntax alone, but whether privileged database actions are time-bound, logged, and tied to identity rather than standing credentials.

By the numbers:
- Only 5.7% of organisations have full visibility into their service accounts.
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
Questions worth separating out
Q: How should security teams control PostgreSQL table administration in production?
A: Security teams should treat PostgreSQL table administration as privileged access, not routine developer activity.
Q: Why do PostgreSQL table privileges increase IAM risk?
A: PostgreSQL table privileges increase IAM risk because the same access that creates or changes schema can also destroy data or expand an application’s blast radius.
Q: What should teams check when duplicate key errors appear after table changes?
A: Teams should check whether the table’s auto-generated sequence is out of sync with existing rows, especially after manual inserts or data migrations.
Practitioner guidance
- Separate table-change rights from everyday database access Grant CREATE, ALTER, and DROP privileges only to identities that truly need them, and keep production rights narrower than development rights.
- Time-box privileged PostgreSQL sessions Use just-in-time access for schema changes and revoke permissions automatically after the maintenance window closes.
- Log full sessions for destructive commands Capture the full SQL session for table creation, alteration, and deletion so each action is tied to an identity and timestamp.

PostgreSQL table creation and access control gaps teams miss?

PostgreSQL table administration is an NHI governance problem disguised as a database task. The article is correct to treat CREATE TABLE as foundational, but the stronger risk signal is who can create, alter, or drop tables in production. Database users, service accounts, and automation frequently outlive the task they were created for, which turns administrative convenience into persistent exposure. Practitioners should treat database privilege as lifecycle-governed NHI access, not as a one-time setup decision.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to Ultimate Guide to NHIs.
- Also from our research: Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
A question worth separating out:
Q: How do audit trails help with PostgreSQL access governance?
A: Audit trails help by showing who did what, when, and from which governed session. For PostgreSQL, that means a table creation or drop can be tied back to an identity instead of a shared admin path. The result is stronger accountability, easier incident review, and better compliance evidence.
