PgBouncer vs Sonic: at a glance
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.
What is Sonic?
Sonic yanks two releases in a day, then ships faster ingest and new count commands.
Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.

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.
Sonic
2.5DEVOPS
Sonic yanks two releases in a day, then ships faster ingest and new count commands.
◆ Current state
Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.
◆ Where it's heading
The 1.x line is moving fast on ingest performance and correctness for high-scale and non-English users, at the cost of some unstable releases. Experimental APIs are being tested in production before they reach official builds.
◆ Prediction
Expect the experimental high-scale PUSH features to graduate out of the feature flag in a later 1.x; when is unclear.
