another section if required by the platform (instead of the old way of building them in section "l" and always transforming them to the platform-specific section). This speeds up the installation on common platforms, and it avoids some funny business with the man page tools and build process.

This command loads a shared library file into the <productname>PostgreSQL</>
|
|
server'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
|
|
server first loaded it. To make use of the shared library,
|
|
function(s) in it need to be declared using the <xref
|
|
linkend="sql-createfunction" endterm="sql-createfunction-title">
|
|
command.
|

</para>

<para>
|
|
The file name is specified in the same way as for shared library
|
|
names in <xref linkend="sql-createfunction" endterm="sql-createfunction-title">; in particular, one
|
|
can rely on a search path and automatic addition of the system's standard
|
|
shared library file name extension. See <xref linkend="xfunc-c"> for
|
|
more information on this topic.
