How do I get my PostgreSQL connection string?

In your database provider's dashboard, click Connect to retrieve your connection string. It typically looks like: postgresql://user:password@host:5432/dbname.

Which connection method should I use?

Select the Transaction pooler option. This ensures compatibility with stateless applications and allows dbdiagramr to detect connections properly.

What if I forgot my database password?

Regenerate your password in the Shared pooler section of your database provider's dashboard and copy-paste the new credentials into your connection string.

Why format your SQL

Readable diffs — formatted migrations produce clean pull-request diffs instead of single-line noise
Faster debugging — a misplaced JOIN or WHERE is obvious when every clause starts on its own line
Team consistency — one style for every query, enforced in seconds rather than by convention docs nobody reads
Log triage — paste a 400-character query from your app logs and actually read it

Frequently asked questions

What does the SQL formatter do?

It takes messy SQL — single-line queries from logs, ORM output, or hand-written DDL — and re-indents it with consistent keyword casing and line breaks. The meaning of your query never changes, only the layout.

Is my SQL private?

Yes. Formatting runs entirely in your browser with no server round-trip. Your SQL is never uploaded, stored, or logged.

Which SQL dialect is supported?

PostgreSQL. The formatter understands Postgres-specific syntax including dollar-quoted strings, casts, and procedural blocks.

Can it format SELECT queries or only CREATE TABLE?

Both. SELECTs, JOINs, CTEs, DDL, migrations — anything valid PostgreSQL formats correctly.

Should keywords be uppercase or lowercase?

There is no technical difference — Postgres is case-insensitive for keywords. UPPERCASE is the traditional DBA style; lowercase matches modern dbt-style analytics codebases. Pick one and enforce it. The formatter supports both plus preserve.
