Loads a shared library file into the PostgreSQL backend's address

space. If the file had been loaded previously, it is first
|
|
|
|
unloaded. This command is primarily useful to unload and reload a

|
|
|
shared library file that has been changed since the backend first
|
|

loaded it. To make use of the
|

shared library, function(s) in it need to be declared using the <xref
