Unless you're digging deep into the parts of the kernel which do memory management and mode switching, you won't have a genuine need for assembly language, but there is some value in learning it. In assembly you see the mechanics of how everything is declared as physical memory -- local variables in C are stack-segment variables in assembly, global variables in C are data-segment ones in assembly, functions are memory addresses in code-segment in both C and assembly, etc, etc. C is technically not dependent on stacks or segments, but I dare you to show me a modern system which doesn't have these in some way.

amd64 is x86 with more and larger registers. Most instructions are the same, but more options are allowed for them.

DROPLANG(1)						  PostgreSQL Client Applications					       DROPLANG(1)

NAME
droplang - remove a PostgreSQL procedural language SYNOPSIS
droplang [ connection-options... ] langname [ dbname ] droplang [ connection-options... ] --list | -l dbname DESCRIPTION
droplang is a utility for removing an existing programming language from a PostgreSQL database. droplang can drop any procedural language, even those not supplied by the PostgreSQL distribution. Although backend programming languages can be removed directly using several SQL commands, it is recommended to use droplang because it performs a number of checks and is much easier to use. See DROP LANGUAGE [drop_language(7)] for more. OPTIONS
droplang accepts the following command line arguments: langname Specifies the name of the backend programming language to be removed. [-d] dbname [--dbname] dbname Specifies from which database the language should be removed. The default is to use the database with the same name as the current system user. -e --echo Displays SQL commands as they are executed. -l --list Shows a list of already installed languages in the target database (which must be specified). droplang also accepts the following command line arguments for connection parameters: -h host --host host Specifies the host name of the machine on which the server is running. If host begins with a slash, it is used as the directory for the Unix domain socket. -p port --port port Specifies the Internet TCP/IP port or local Unix domain socket file extension on which the server is listening for connections. -U username --username username User name to connect as -W --password Force password prompt. ENVIRONMENT
PGDATABASE PGHOST PGPORT PGUSER Default connection parameters. DIAGNOSTICS
Most error messages are self-explanatory. If not, run droplang with the --echo option and see under the respective SQL command for details. Check also under psql(1) for more possibilities. NOTES
Use createlang(1) to add a language. EXAMPLES
To remove pltcl: $ droplang pltcl dbname SEE ALSO
