Error: We haven't implemented a converter for tsvector

[seantalbot-jisc]

Describe the bug Synth does not support postgres tsvector.

To Reproduce Steps to reproduce the behavior:

1. Schema (if applicable)

CREATE TABLE title_version (
    id INTEGER PRIMARY KEY GENERATED BY DEFAULT AS IDENTITY,
    field_value VARCHAR(550) NOT NULL
   -- etc
);

ALTER TABLE
    title_version
ADD COLUMN
    field_value_ts_vector_english tsvector GENERATED ALWAYS AS (
        to_tsvector('english', lower(coalesce(field_value, '')))
    ) STORED;

When attempting to use synth to import the schema:

synth import --from <postgres-uri> --schema public testing

2. See error

   Error: We haven't implemented a converter for tsvector

Expected behavior Synth should support tsvector when importing an existing postgres schema.
