You might have a corrupted TOAST table. Have you had any hardware
problems, database or system crashes, etc., lately? Do you see any
unusual messages in the database or system log files? What are the
results of the following queries?

SELECT reltoastrelid::regclass
FROM pg_class
WHERE relname = 'measured_bioassay_base';

(The following query refers to the above result as pg_toast.pg_toast_XXXXXX.)

SELECT xmin, xmax, chunk_seq, length(chunk_data)
FROM pg_toast.pg_toast_XXXXXX
WHERE chunk_id = 144391872;
