Due to the permissions being set in this fashion, only the owner or a member of the possessing group can load the library. ![]() The binaries involved in that example were 32-bit and installed as mode 750 instead of 755. In the case of the plperl example, above, check your umask and the permissions of the binaries in your PostgreSQL installation. The default allows for less than 256 MB in the heap as it shares a single segment with the stack. These 32-bit processes are limited to 4 GB of memory laid out in 256 MB segments using one of a few models. This does not depend upon hardware type or kernel in use. By default, all binaries built on AIX are 32-bit. The overall cause of all these problems is the default bittedness and memory model used by the server process. Running as a non-owner in the group possessing the PostgreSQL installation:ĮRROR: could not load library "/opt/dbs/pgsql/lib/plperl.so": Bad addressĪnother example is out of memory errors in the PostgreSQL server logs, with every memory allocation near or greater than 256 MB failing. For example, running as the owner of the PostgreSQL installation:ĮRROR: could not load library "/opt/dbs/pgsql/lib/plperl.so": A memory address is not in the address space for the process. One example is loading of extensions failing with unusual errors. You can have a server with many multiples of gigabytes of RAM free, but still get out of memory or address space errors when running applications. If you want to use command-line tools like psql, you can add PostgreSQL to the path after installation.AIX can be somewhat peculiar with regards to the way it does memory management. Alternatively, clear the Stack Builder check box and select Finish to complete the PostgreSQL installation without launching Stack Builder.īy default, the installer doesn't modify the system path.

When you're satisfied with the settings summary, select Next. If necessary, use the Back button to return to a previous dialog box to modify a setting.

If you already created a service account with the name postgres, you must specify the same password as the existing password for the postgres service account. The PostgreSQL service account is named postgres. PostgreSQL runs as a service in the background. PostgreSQL uses the password specified on the Password window for both the database superuser and the PostgreSQL service account.
