Обсуждение: Annoying messages when copy sql code to psql terminal

Whenever I use copy-paste to run code in a terminal window that is
running psql, and the code contains a row like

IF FOUND THEN

then I get the words

ABORT        CHECKPOINT   COMMIT       DECLARE      EXECUTE
INSERT       MOVE         REINDEX      ROLLBACK     SHOW
UPDATE
ALTER        CLOSE        COPY         DELETE FROM  EXPLAIN
LISTEN       NOTIFY       RELEASE      SAVEPOINT    START
VACUUM
ANALYZE      CLUSTER      CREATE       DROP         FETCH        LOAD
       PREPARE      RESET        SELECT       TRUNCATE
BEGIN        COMMENT      DEALLOCATE   END          GRANT        LOCK
       REASSIGN     REVOKE       SET          UNLISTEN

That must be some kind of display of possible stuff to write after
"THEN" but it is very annoying. How to turn it of?

I'd guess the next line of code starts with a tab character and hence
psql is just tab completing the (empty) line.  If you don't want this to
happen, you can disable table completion.  From the man page:

       If
       for some reason you do not like the tab completion, you can turn it off
       by putting this in a file named .inputrc in your home directory:

       $if psql
       set disable-completion on
       $endif

As an aside, there isn't an "if" statement in SQL.

Either avoid copying/pasting tabs, or turn off readline
(-n option to psql, I think, but check the manual).

There's probably a way to turn off tab-completion without
disabling readline altogether, but I don't know how offhand.

This can be done by adding

$if psql
   set disable-completion on
$endif

to .inputrc.

As others have noted, you have tabs in your sql source.  I'd advise if
possible, not to use the tab character in sql, for this and other
reasons.

For example, another reason tabs are annoying are how your function
sources show up in '\df+' (escaped).  iirc you can get around this
with '\x', but why bother with that?  Also, I am not suggesting not to
indent your sql, just not to use the tab character.

Almost every decent text editor has the option to use spaces in place
of tabs.  Even Nano can do it.
