Neon's SQL Editor has been upgraded to support Postgres's introspection commands, like the psql backslash commands, through a serverless driver that operates in web environments without raw TCP connections. Initially, these commands, implemented in the psql client C code, were not supported in the web-based SQL Editor, leading to syntax errors. To address this, the C code for these commands was translated into JavaScript using regular expressions, allowing them to function in the browser. This development involved parsing SQL queries in the client-side to handle introspection commands separately and creating an open-source package to efficiently identify comments and statement-terminating semicolons in SQL strings. Users can now utilize these introspection commands in the Neon console, with additional features like viewing underlying SQL queries when running commands. The initiative reflects a pragmatic approach to integrating Postgres features into Neon’s web-based tools, aiming to enhance user experience and efficiency in managing database queries.
