If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable

Also, isimmv columns is added to pg_matviews system view.
