Barman vs PgBouncer
A side-by-side editorial comparison of Barman and PgBouncer — release velocity, themes, recent moves, and the top alternatives to consider.
Barman vs PgBouncer: at a glance
What is Barman?
Barman 3.20.1 closes a CVE that let a writable catalog delete unrelated snapshots.
Barman 3.20.1 fixes CVE-2026-93853: Barman trusted snapshot IDs from the backup catalog, so anyone able to overwrite backup.info could make it delete unrelated cloud snapshots with Barman's own credentials. It now checks snapshot names against provider metadata before deleting. 3.20.0 in August raised the Python floor to 3.12 and added SSE-C encryption, parallel GCS uploads and S3 Outposts support.
What is PgBouncer?
PgBouncer patches a SCRAM flaw that let a known user log in as an admin
PgBouncer's 1.26 line pairs features with a heavy security load. 1.26.0 tracks search_path and default_transaction_read_only by default, so one client's SET no longer leaks to others in transaction pooling, adds pool_idle_timeout and per-user query_wait_timeout, and removes the old online-restart takeover in favour of rolling restarts. It also fixed three CVEs. Three weeks later, 1.26.1 fixed three more, including one where a user with a password in auth_file could log in as any other SCRAM user, admins included.

Barman
0.0DEVOPS
Barman 3.20.1 closes a CVE that let a writable catalog delete unrelated snapshots.
◆ Current state
Barman 3.20.1 fixes CVE-2026-93853: Barman trusted snapshot IDs from the backup catalog, so anyone able to overwrite backup.info could make it delete unrelated cloud snapshots with Barman's own credentials. It now checks snapshot names against provider metadata before deleting. 3.20.0 in August raised the Python floor to 3.12 and added SSE-C encryption, parallel GCS uploads and S3 Outposts support.
◆ Where it's heading
After closing the cloud backup-and-restore loop in 3.18 and 3.19, Barman is hardening it for regulated, least-privilege setups: customer-supplied keys, data kept on Outposts, and now a fix aimed exactly at deployments where the uploading identity has fewer rights than Barman. Releases come roughly every two to three months.
◆ Prediction
A 3.21.0 feature release is the likely next step on the usual cadence, probably continuing cloud storage and retention safety work.

PgBouncer patches a SCRAM flaw that let a known user log in as an admin
◆ Current state
PgBouncer's 1.26 line pairs features with a heavy security load. 1.26.0 tracks search_path and default_transaction_read_only by default, so one client's SET no longer leaks to others in transaction pooling, adds pool_idle_timeout and per-user query_wait_timeout, and removes the old online-restart takeover in favour of rolling restarts. It also fixed three CVEs. Three weeks later, 1.26.1 fixed three more, including one where a user with a password in auth_file could log in as any other SCRAM user, admins included.
◆ Where it's heading
Since 1.25.1 every release has carried CVE fixes in the authentication and packet-handling paths, and 1.26.1 found a second instance of a bug class fixed weeks earlier. The project is auditing its pre-auth surface in public, while 1.26.0 shows it still cleaning up long-standing pooling surprises.
◆ Prediction
More security point releases are likely while the auth and buffer code is under review; the entries give no sign of the next feature release.
