Package "libpq-oauth"

PostgreSQL C client library - OAuth flow
libpq-oauth is an optional module for libpq5 implementing the Device
Authorization flow for OAuth clients (RFC 8628). It is maintained as
its own shared library in order to isolate its dependency on libcurl.
(End users who don't want the Curl dependency can simply choose not
to install this module.)

If a connection string allows the use of OAuth, and the server asks
for it, and a libpq client has not installed its own custom OAuth
flow, libpq will attempt to delay-load this module using dlopen() and
the following ABI. Failure to load results in a failed connection.

PostgreSQL is an object-relational SQL database management system.
