+// Package pgconn is a low-level PostgreSQL database driver.
+/*
+pgconn provides lower level access to a PostgreSQL connection than a database/sql or pgx connection. It operates at
+nearly the same level is the C library libpq.
+
+Establishing a Connection
+
+Use Connect to establish a connection. It accepts a connection string in URL or DSN and will read the environment for
+libpq style environment variables.
+
+Executing a Query
+
+ExecParams and ExecPrepared execute a single query. They return readers that iterate over each row. The Read method
+reads all rows into memory.
+
+Executing Multiple Queries in a Single Round Trip
+
+Exec and ExecBatch can execute multiple queries in a single round trip. The return readers that iterate over each query
+result. The ReadAll method reads all query results into memory.
+
+Context Support
+
+All potentially blocking operations take a context.Context. If a context is canceled while a query is in progress the
+method immediately returns. In the background a cancel request will be sent to the PostgreSQL server. If the
+cancellation fails or hangs for more than a short time (approximately 15 seconds) the connection will be closed. It is
+safe to use the connection while this background cancellation is in progress. Any calls will block until the
+cancellation and resynchronization is complete (and those calls can be aborted by a context cancellation).
