Then read the psql docs.  Your version has \if and you’ll find server
version listed as the available client variables.

I was hoping for something like

If server_version >= X:
     CREATE OR REPLACE TRIGGER...
else:
     CREATE TRIGGER...

Python-like syntax here as I'm not sure how to do it properly...

Thank you.

psql's \if doesn't (yet) have any native expression evaluation
ability, so you have to farm out the ">=" comparison.  The
psql docs suggest relying on the server to do it, which would
go along the lines of

select current_setting('server_version_num')::int >= 130000 as v13
\gset
\if :v13
   ... do something
\else
   ... do something else
\endif

You could also do the comparison client-side, along the lines of

\set v13 `expr :SERVER_VERSION_NUM \>= 130000`
\if :v13
  ... etc

But that introduces assorted platform dependencies and requires
close attention to correct shell quoting, so it's seldom
preferable IMO.

Thank for the code.

2 things, however.
1. Apparently CREATE OR RELACE TRIGGER syntax is available since v17, which
is the current one. So I hadto adjust the numbers.. 😀
2. Is there a way to do CREATE TRIGGER IF NOT EXIST for the earlier version?

Thank you.

No.  You have to drop the trigger if it does exist and then create the new
one.

Well, you can always query the catalogs directly to answer the question
“does this trigger exist”.

Hi,

[code]
SELECT current_setting('server_version_num')::int > 130000 as v13
\gset
\if :v13
   CREATE OR REPLACE TRIGGER playersinleague_insert AFTER INSERT ON
playersinleague WHEN new.current_rank IS NULL
   BEGIN
           UPDATE playersinleague SET current_rank = 1 + (SELECT
coalesce( max( current_rank ), 0 ) FROM playersinleague WHERE id =
new.id) WHERE rowid = new.rowid;
psql:draft_pg.sql:44265: ERROR:  syntax error at or near "TRIGGER"
LINE 1: CREATE OR REPLACE TRIGGER playersinleague_insert AFTER INSER...
                         ^
[/code]

What am I doing wrong?

Thank you.

the test should be

SELECT current_setting('server_version_num')::int > =140000 as v14

\if :v14
 ...

CREATE OR REPLACE is supported from PostgreSQL 14

IOW, you can’t use >130000 because that will match v13.1 which is 130001 in
integer format.

    BEGIN
        UPDATE playersinleague SET current_rank = 1 + (SELECT coalesce(
max( current_rank ), 0 ) FROM playersinleague WHERE id = new.id) WHERE
rowid = NEW.rowid;
        UPDATE playersinleague SET original_rank = current_rank WHERE rowid
= new.rowid;
    END;
\endif
[/code]

And I'm getting this:

[code]
\else
   DROP TRIGGER IF EXISTS playersinleague_insert ON playersinleague;
psql:draft_pg.sql:44269: NOTICE:  trigger "playersinleague_insert" for

   BEGIN
           UPDATE playersinleague SET current_rank = 1 + (SELECT coalesce(

rowid = new.rowid;
psql:draft_pg.sql:44272: ERROR:  syntax error at or near "new"

                                                            ^

[/code]

What is the problem niw?

Thank you.

When the syntax shows parentheses you are required to write them.

  [ WHEN ( *condition* ) ]

	CREATE TRIGGER playersinleague_insert AFTER INSERT ON playersinleague WHEN ( new.current_rank IS NULL )

Really?:

"CREATE [ OR REPLACE ] [ CONSTRAINT ] TRIGGER name ..."
