Question

Is there any other way to search for a certain value in an integer[] column in Postgres?

My currently installed Postgres version does not allow the following statement:

SELECT * FROM table WHERE values *= 10;

Array examples:

'{11043,10859,10860,10710,10860,10877,10895,11251}'
'{11311,10698,10697,10710,10712,10711,10708}'

The statement should return every row where the array contains '10710'.

Answer 1

For equality checks you can simply:

SELECT * FROM tbl WHERE 10 = ANY (values);

Read about ANY/SOME in the manual.
For big tables / big arrays consider array operators with index support, like:

SELECT * FROM tbl WHERE values @> '{10}'::int[];

See:

• Check if value exists in Postgres array
• IN vs ANY operator in PostgreSQL

For integer arrays consider the additional module intarray:

• Compare arrays for equality, ignoring order of elements
