Unable to get past "Database error 42883: operator does not exist: text = boolean"

[nsrandom]

Hi, I managed to build pgcharts on my Mac, and set it up with an existing database.
But all queries are failing with the following error.

Date/time: 2022-04-01-12:10!
An unhandled error condition has been signalled:
Database error 42883: operator does not exist: text = boolean
HINT: No operator matches the given name and argument types. You might need to add explicit type casts.
QUERY: (SELECT * FROM db WHERE (dbname = false))

17: ("foreign function: funcall1")

My query is as simple as:

SELECT * FROM punters;

where the punters table is defined as:

CREATE TABLE punters (
    year integer not null,
    month integer not null,
    day integer not null,
    name text not null,
    hands integer,
    chips integer not null,
    amount numeric(5,2) not null,
    buyins integer
);

I feel like I might be making some small obvious mistake, but I can't figure it out. StackOverflow seems to say that I might be using non standard table columns, but I am only using standard data types afaict.

Any help would be much appreciated.
