Do coding agents recommend Azure Database for PostgreSQL Flexible Server?
Azure Database for PostgreSQL Flexible Server was chosen in 9% of 496 judged databases sessions, ranking second.
Azure Database for PostgreSQL Flexible Server was chosen in 9% of 496 judged databases sessions, ranking second. It was also raised as a candidate in 27 further sessions without being chosen.
This page reports what happened when Claude Code, Codex, Cursor, Grok Build CLI and Muse Code had to solve a problem in databases inside a realistic codebase. Not what a chat assistant says about Azure Database for PostgreSQL Flexible Server. What an agent actually installed.
One thing to read first: every one of those wins came from a single codebase. That is a result about one repository rather than about databases in general, and the splits below cannot separate the two. Treat them as a description of that repository.

What this means
Agents almost never raise Azure Database for PostgreSQL Flexible Server without choosing it: 27 sessions raised against 45 chosen. When it gets considered, it usually wins. The constraint is how rarely it gets considered at all, which is a presence problem: templates, framework integrations and pages that answer the configuration and production questions agents actually search for.
Where these numbers come from
The 496 sessions in databases are part of a published set of 15,051, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.
Every databases run can be replayed on the board.
If you work on Azure Database for PostgreSQL Flexible Server: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts.

Common questions
Do coding agents recommend Azure Database for PostgreSQL Flexible Server?
Yes. Azure Database for PostgreSQL Flexible Server was chosen in 45 of the 496 judged sessions in databases, a 9% install share, ranking second in its category.
Does Claude Code recommend Azure Database for PostgreSQL Flexible Server?
In 18 of the 147 sessions in databases run with Claude Code, which is 12%.
Do different coding agents treat Azure Database for PostgreSQL Flexible Server differently?
Not much. Claude Code, Codex, Cursor and Muse Code chose it at similar rates, between 6% and 12% of their runs.
How was this measured?
Real coding agents at pinned versions were run in sandboxes inside 92 realistic codebases and asked to solve real tasks. A simulated project owner approved or questioned each recommendation before any code was written, and a judge from a model family that builds none of the agents read every session blind.
How often is Azure Database for PostgreSQL Flexible Server considered but not chosen?
It was raised as a candidate in 27 sessions without being chosen, and chosen in 45. That is a 63% conversion from considered to chosen.
Where this comes from
Armature ran 15,051 judged sessions with Claude Code, Codex, Cursor, Grok Build CLI and Muse Code inside 92 realistic codebases, and published every run. The numbers on this page come from that work.
