Les instruments serveurs ne sont pas installés
The server lacks instrumentation functions.
pgAdmin III uses some support functions that are not available by default in all PostgreSQL versions. These enable some tasks that make life easier when dealing with log files and configuration files.
When you install PostgreSQL 8.0 or up using the Windows installer, you just need to select the "admin" or "adminpack" module.c
When compiling from source, the necessary files can be found in the xtra subdirectory of the pgAdmin source tree. For PostgreSQL 8.0, copy the admin directory under the postgresql contrib source directory, make and make install from there. For PostgreSQL 8.1, use the admin81 directory for that.
PostgreSQL 8.2 and above include the instrumentation functions in the "adminpack" contrib module. After the module is installed, you need to create the instrumentation functions in your maintenance database using the admin.sql script (admin81.sql for PostgreSQL 8.1) which are usually located in the pgsql share directory (e.g. /usr/local/pgsql/share)
Extended server instrumentation is not supported for PostgreSQL 7.3 and 7.4.
