Is it possible you have more than one row where state = 'CA'? Putting a LIMIT 1 would then restrict to only 1 row.
Have you tried with no limit? IE: SELECT new_col FROM data;

Just added a new bytea type column to an existing psql table and populated the column entirely with row data. Running into some strange query results:
When I select the newly added column by itself I get all the data as expected:
SELECT new_col FROM data LIMIT 1; Result: \x8481e7dec3650040b....When I try to filter with 'where' on another column in the table, I get the values from the other columns as expected but empty from my new_column:
SELECT id, state, new_col FROM data WHERE state='CA' limit 1; Result: 123456_1; CA; EMPTY ROWThe reverse is also true. If I select my new column in combination with other columns with no 'where' I get the correct value from my new column but empty for the other columns:
SELECT id, state, new_col FROM data limit 1; Result: EMPTY ROW; EMPTY ROW; \x8481e7dec3650040b....Thanks to anyone with advice!
