Changes

This PR documents the new connection string auto-populate feature for Data Warehouse database sources, introduced in PostHog/posthog#56801.

Users can now paste a connection string URL when configuring database sources, and the form fields will auto-populate. This was previously only documented for Postgres, but now applies to all released database sources.

Updated pages

  • MySQL (contents/docs/cdp/sources/mysql.mdx) - Added tip for mysql:// URLs with SSL query parameters
  • Microsoft SQL Server (contents/docs/cdp/sources/microsoft-sql-server.mdx) - Added tip for mssql:// and sqlserver:// URLs
  • Snowflake (contents/docs/cdp/sources/snowflake.mdx) - Added tip for snowflake:// URLs (password auth only)
  • ClickHouse (contents/docs/cdp/sources/clickhouse.mdx) - Added tip for https://, http://, clickhouse://, and clickhouses:// URLs with port derivation info
  • PostgreSQL (contents/docs/cdp/sources/postgres.mdx) - Added tip for postgres:// and postgresql:// URLs (existing feature, now documented)

Reflects PR #56801 which added connection string parsers for MySQL
and other database sources. The MySQL parser accepts mysql:// URLs
and auto-populates host, port, database, user, password, and SSL fields.
Document that users can paste a postgres:// or postgresql:// connection
string to auto-populate host, port, database, user, and password fields.
This feature existed before but was not documented.
