-.SH NAME
-load \(em dynamically load an object file
-.SH SYNOPSIS
-.nf
-\fBload\fR "filename"
-.fi
-.SH DESCRIPTION
-.BR Load
-loads an object (or ".o") file into Postgres's address space. Once a
-file is loaded, all functions in that file can be accessed. This
-function is used in support of ADT's.
-.PP
-If a file is not loaded using the
-.BR load
-command, the file will be loaded automatically the first time the
-function is called by Postgres.
-.BR Load
-can also be used to reload an object file if it has been edited and
-recompiled. Only objects created from C language files are supported
-at this time.
-.SH EXAMPLE
-.nf
---
---Load the file /usr/postgres/demo/circle.o
---
-load "/usr/postgres/demo/circle.o"
-.fi
-.SH CAVEATS
-Functions in loaded object files should not call functions in other
-object files loaded through the
-.BR load
-command, meaning, for example, that all functions in file A should
-call each other, functions in the standard or math libraries, or in
-Postgres itself. They should not call functions defined in a different
-loaded file B. This is because if B is reloaded, the Postgres loader is
-not \*(lqsmart\*(rq enough to relocate the calls from the functions in A into
-the new address space of B. If B is not reloaded, however, there will
-not be a problem.
-.PP
-On DECstations, you must use
-.IR /bin/cc
-with the \*(lq-G 0\*(rq option when compiling object files to be
-loaded.
-.PP
-Note that if you are porting Postgres to a new platform, the
-.BR load
-command will have to work in order to support ADTs.
