QuestDB supports the Postgres wire protocol. As a result, QuestDB is capable of running most of Postgres queries. This means that you can use your favorite Postgres client or driver with QuestDB, at no extra cost.

The storage model used by Postgres is fundamentally different to the one used by QuestDB. Some features that exists for Postgres do not apply to QuestDB.

Compatibility

List of supported features

• Querying (all types expect BLOB)
• Prepared statements with bind parameters (check for specific libraries below)
• INSERT statements with bind parameters (same)
• DDL execution
• Batch inserts with JDBC
• Plain authentication

Examples which demonstrate how to use Postgres clients in a number of different languages can be found on the following pages:

• Connect shows how to create a connection to QuestDB using Postgres
• Insert data demonstrates how to use paramaterized queries and prepared statements to insert data
• Query data shows how to run queries against tables

List of unsupported features

• SSL
• Remote file upload (COPY from stdin)
• UPDATE and DELETE statements
• BLOB transfer
