bigintarray

Like intarray module for PostgreSQL, but for Big Integers

typical installation

git clone https://github.com/DanielJDufour/bigintarray

cd bigintarray

make install

make installcheck

psql -c "CREATE EXTENSION bigintarray";

alternative installation

Sometimes you aren't allowed to add custom extensions, like in a cloud environment. In that case, you can install by either copying the contents of bigintarray--0.0.1.sql into your database initialization code or running the following commands

# download code for the extension
wget https://raw.githubusercontent.com/DanielJDufour/bigintarray/main/bigintarray--0.0.1.sql

# create functions and operators by directly executing SQL statements
psql -h 0.0.0.0 -p 5432 --username postgres database < ./bigintarray--0.0.1.sql;

descriptions are based on intarray.

Operator	Description	Status
bigint[] && bigint[] → boolean	Do arrays overlap (have at least one element in common)?	✓ (Built-In)
bigint[] @> bigint[] → boolean	Does left array contain right array?	✓ (Built-In)
bigint[] <@ bigint[] → boolean	Is left array contained in right array?	✓ (Built-In)
# bigint[] → integer	Returns the number of elements in the array	✓
bigint[] # bigint → integer	Returns index of the first array element matching the right argument, or 0 if no match. (Same as idx function.)	X
bigint[] + bigint → bigint[]	Adds element to end of array.	✓
bigint[] + bigint[] → bigint[]	Concatenates the arrays.	✓
bigint[] - bigint[] → bigint[]	Removes elements of the right array from the left array.	✓
bigint[] | bigint → bigint[]	Computes the union of the arguments.	✓
bigint[] | bigint[] → bigint[]	Computes the union of the arguments.	✓
bigint[] & bigint[] → bigint[]	Computes the intersection of the arguments.	✓
bigint[] @@ query_bigint → boolean	Does array satisfy query? (see below)	X
