Обсуждение: psql: why not pset PROMPT[0-2] ?

(In psql:)
I need to modify the 2nd prompt. So i looked at the sources:
I leave the validity test (of the name of the option/param) to SetVariable !!



Here is the patch:

diff -c /internet/cvs/pgsql/src/bin/psql/command.c.~1~ /internet/cvs/pgsql/src/bin/psql/command.c

+ 
+     /* toggle use of pager */
+     else if (strncmp(param, "PROMPT",6) == 0)
+     {
+       SetVariable(pset.vars, param, value);    /* SetVariable takes care of whether param is actually valid !! */
+     }
+ 
+ 
+ 
+      else     {         psql_error("\\pset: unknown option: %s\n", param);

Because pset sets parameters of the table output.  Prompts have nothing to
do with table output.
