// 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. They return readers that iterate over each query
result. The ReadAll method reads all query results into memory.

Pipeline Mode

Pipeline mode allows sending queries without having read the results of previously sent queries. It allows
control of exactly how many and when network round trips occur.

Context Support

All potentially blocking operations take a context.Context. If a context is canceled while the method is in progress the
method immediately returns. In most circumstances, this will close the underlying connection.

The CancelRequest method may be used to request the PostgreSQL server cancel an in-progress query without forcing the
client to abort.
