pg_parameter_status — Looks up a current parameter setting of the server
Looks up a current parameter setting of the server.
Certain parameter values are reported by the server automatically at
connection startup or whenever their values change. pg_parameter_status() can be
used to interrogate these settings. It returns the current value of a
parameter if known, or false if the parameter is not known.
Parameters reported as of PostgreSQL 8.0 include server_version,
server_encoding, client_encoding,
is_superuser, session_authorization,
DateStyle, TimeZone, and integer_datetimes.
(server_encoding, TimeZone, and
integer_datetimes were not reported by releases before 8.0.) Note that
server_version, server_encoding and integer_datetimes
cannot change after PostgreSQL startup.
PostgreSQL 7.3 or lower servers do not report parameter settings,
pg_parameter_status()
includes logic to obtain values for server_version and
client_encoding
anyway. Applications are encouraged to use pg_parameter_status() rather than ad
hoc code to determine these values.
On a pre-7.4
PostgreSQL server, changing client_encoding via SET after connection startup will
not be reflected by pg_parameter_status().

nesnesi. bağlantı belirtilmemişse öntanımlı bağlantı
kullanılır. Öntanımlı bağlantı pg_connect()
veya pg_pconnect() işleviyle kurulmuş son bağlantıdır.
PHP 8.1.0 ve sonrasında, öntanımlı bağlantının kullanımı önerilmemektedir.

server_encoding, client_encoding,
is_superuser, session_authorization,
DateStyle, TimeZone, and
