DIRECT TO POSTGRESQL
Everything works together.
BlueTusk talks directly to PostgreSQL and does not hide another provider underneath.
CONNECT YOUR WAY
Secure connections, clearly configured.
Connection featureWhat BlueTusk supportsWhat you control
CredentialsStatic values, callbacks, password files, and cloud token providersChoose where credentials come from; BlueTusk keeps them out of logs
TLSServer certificate checks and client certificatesChoose which certificates your application trusts
Multi-hostConnect to the right server and fail over between configured hostsChoose the required server role; BlueTusk verifies it
PoolingReusable connection pools with limits, reset, and health checksChoose pool size and whether session state can be retained
AuthenticationPassword, OAuth, Kerberos/SSPI, and supported legacy methodsThe server and selected login method determine what is available
POSTGRESQL TYPES
Use the database types you already rely on.
Values keep PostgreSQL precision and behavior.
Supports one-dimensional and multidimensional PostgreSQL arrays.
Keeps inclusive, exclusive, empty, and unbounded ranges intact.
Text and binary paths with typed parameters.
Works with PostgreSQL network addresses as typed values.
Use PostgreSQL full-text search values in ADO.NET and EF Core.
Register your .NET types once when the data source is created.
Infinity and interval structure preserve server behavior.
MORE THAN QUERIES
Bulk data, notifications, and replication are built in.
Use dedicated, tested APIs for high-volume and real-time database work.
BULK DATA
COPY
Import or export large amounts of data efficiently, with typed values and cancellation.
Read the technical guideFASTER BATCHES
Pipeline mode
Send groups of commands with fewer network waits while keeping results and errors in order.
Read the technical guideMESSAGING
LISTEN / NOTIFY
Receive PostgreSQL notifications asynchronously while the connection stays healthy.
Read the technical guideLARGE VALUES
Sequential + large objects
Stream large fields and objects without loading the entire value into memory.
Read the technical guideDATABASE CHANGES
Logical replication
Read committed PostgreSQL changes for Streams, Sync, Live, or your own processing.
Read the technical guideIDENTITY
Cloud credentials
Use short-lived AWS, Azure, or Google Cloud login tokens instead of stored passwords.
Read the technical guideFAMILIAR ADO.NET
Create one data source and reuse it.
This is the public 1.x API. Automated checks keep the packages, API reference, examples, and compatibility promises in sync.
