Comment: I think 0 and 1 are the correct values here?

[question] Where did you get those values from? See here the values returned when querying are string values.

Where did you get those values from?

A guess. Looking further into it I see there are multiple values that are acceptable based on the redshift docs on the Boolean type

State	Valid literal values	Storage
True	TRUE 't' 'true' 'y' 'yes' '1'	1 byte
False	FALSE 'f' 'false' 'n' 'no' '0'	1 byte
Unknown	NULL	1 byte

I'm going to make it true/false

VARCHAR(max) isn’t used anywhere else in the data dictionary and isn’t a valid type in Postgres/Redshift-style dialects (this repo consistently uses sized VARCHAR(n) like VARCHAR(255) / VARCHAR(4096)). Please align the title datatype with the actual column type and existing docs conventions (e.g. a sized VARCHAR(n) or TEXT as appropriate).

Suggested change

	| `title` | `VARCHAR(max)` | The tag title | `Open access` |
	| `title` | `VARCHAR(255)` | The tag title | `Open access` |

Anyone else have thoughts on this. I based it on the value used in the PR to add the tags table:

s_rl_tags_: {
    columns: {
      tag_guid: 'varchar(64)',
      title: 'varchar(max)',
      is_active: 'boolean',
