Hi
Respected postgres community members

I have created BRIN index on few columns of the table without any issues. But i am unable to create BRIN index on one column of the table as i got error listed below

[local]:6263 postgres(at)huawei=# CREATE INDEX brin_idx on huawei using brin ("dFetch");
ERROR: data type boolean has no default operator class for access method "brin"
HINT: You must specify an operator class for the index or define a default operator class for the data type.

below is the column description:
Column datatype collation nullable default storage

dFetch boolean false plain

so please help in creating of the BRIN index on above column of the table .

Regards

Why would you want BRIN index on Boolean-type column?
What kind of interval will you specify?
