Diagnose and fix excessive Postgres egress (network data transfer) in a codebase. Use when a user mentions high database bills, unexpected data transfer costs, network transfer charges, egress spikes, "why is my Neon bill so high", "database costs jumped", SELECT * optimization, query overfetching, reduce Neon costs, optimize database usage, or wants to reduce data sent from their database to their application. Also use when reviewing query patterns for cost efficiency, even if the user doesn't explicitly mention egress or data transfer.

Postgres Egress Optimizer

Guide the user through diagnosing and fixing application-side query patterns that cause excessive data transfer (egress) from their Postgres database. Most high egress bills come from the application fetching more data than it uses.

Work the four steps in order: diagnose which queries transfer the most data, analyze the codebase behind them, fix the anti-patterns, then verify nothing broke and the transfer actually dropped.

Step 1: Diagnose

Identify which queries transfer the most data. The primary tool is the pg_stat_statements extension.
