I'm trying to update a Postgres database to set a boolean but I'm getting the following error

No operator matches the given name and argument type(s). You may need to add explicit type casts.

       Column       |            Type             | Modifiers 
--------------------+-----------------------------+-----------
 archived           | boolean                     | 

The column in the db is currently empty so I have no others to use as a comparison.

I've tried the following:

UPDATE table_name SET archived=TRUE WHERE id=52;
UPDATE table_name SET archived='t' WHERE id=52;
UPDATE table_name SET archived='1' WHERE id=52;
UPDATE table_name SET archived='t'::boolean WHERE id=52;

Neither of these have worked.

How do I cast my UPDATE to a boolean?

UPDATE: full error message

play_mercury=# UPDATE opportunities SET archived=TRUE WHERE id=(52,55,35,17,36,22,7,2,27,15,10,9,13,5,34,40,30,23,21,8,26,18,3,42,25,20,41,28,19,14,39,44,16,24,4,33,54,47,29,38,64);
ERROR:  operator does not exist: bigint = record

The problem is in the WHERE id=(52,55,...)

Use: WHERE id IN (52,55,...)


Your WHERE condition is wrong. You need to use IN instead of =

UPDATE opportunities 
  SET archived=TRUE 
WHERE id IN (52,55,35,17,36,22,7,2,27,15,10,9,13,5,34,40,30,23,21,8,26,18,3,42,25,20,41,28,19,14,39,44,16,24,4,33,54,47,29,38,64);


How are you trying this? Via plsql? According to the docs those should be valid and this also works for me:

tmp=# create table bar (a boolean, b int);
CREATE TABLE
tmp=# insert into bar values (TRUE, 1);
INSERT 0 1
tmp=# update bar set a=false where b=1;
UPDATE 1
tmp=# \d bar
      Table "public.bar"
 Column |  Type   | Modifiers 
--------+---------+-----------
 a      | boolean | 
 b      | integer | 
0
