// 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.
|
|
|
|
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.
|
|
A nil context can be passed for convenience. This has the same effect as passing context.Background().
|
|
|
|
The CancelRequest method may be used to request the PostgreSQL server cancel an in-progress query without forcing the
|
|
client to abort.
