The table name

-namespace (optional, defaults to "public")

The database namespace that contains the table

-block_size (optional, defaults to "8192")

Size of BLCKSZ (in bytes) used by the database

This procedure returns a list with 2 items:

1. Size of the table on disk (in bytes), or -1 if the table was not found
2. Number of rows in the table, or -1 if the table was not found
