Thanks for looking at this. I forgot about tab completion.

I think that the change to ALTER TRIGGER is not necessary. AFAICT it
works OK unmodified. In fact, the modified code here:

*** 971,977 **** psql_completion(char *text, int start, int end)     else if (pg_strcasecmp(prev4_wd, "ALTER") == 0 &&
           pg_strcasecmp(prev3_wd, "TRIGGER") == 0 &&              pg_strcasecmp(prev_wd, "ON") == 0) 
!         COMPLETE_WITH_SCHEMA_QUERY(Query_for_list_of_tables, NULL);
     /* ALTER TRIGGER <name> ON <name> */     else if (pg_strcasecmp(prev4_wd, "TRIGGER") == 0 &&
--- 1055,1061 ----     else if (pg_strcasecmp(prev4_wd, "ALTER") == 0 &&              pg_strcasecmp(prev3_wd,
"TRIGGER")== 0 &&              pg_strcasecmp(prev_wd, "ON") == 0) 
!         COMPLETE_WITH_SCHEMA_QUERY(Query_for_list_of_writeables, NULL);
     /* ALTER TRIGGER <name> ON <name> */     else if (pg_strcasecmp(prev4_wd, "TRIGGER") == 0 &&

appears to be unreachable, because it is preceded by
   else if (pg_strcasecmp(prev4_wd, "ALTER") == 0 &&            pg_strcasecmp(prev3_wd, "TRIGGER") == 0)   {
completion_info_charp= prev2_wd;       COMPLETE_WITH_QUERY(Query_for_list_of_tables_for_trigger);   } 

which works for tables and views, and makes the next "elseif"
impossible to satisfy. So I think that block could just be deleted,
right?

Dean
