14 : * DESCRIPTION
15 : * The "DefineFoo" routines take the parse tree and pick out the
16 : * appropriate arguments/flags, passing the results to the
17 : * corresponding "FooDefine" routines (in src/catalog) that do
18 : * the actual catalog-munging. These routines also verify permission
19 : * of the user to execute the command.
20 : *
21 : * NOTES
22 : * These things must be defined and committed in the following order:
23 : * "create function":
24 : * input/output, recv/send functions
25 : * "create type":
26 : * type
27 : * "create operator":
28 : * operators
