| Datum sax_string | ( | PG_FUNCTION_ARGS | ) |
PgSQL wrapper for SAX to easy-to-read string conversion.
It generates string like:
SAX = 'ABCD|C:D|EF09/num_per_letter'
| sax | SAX structure to convert |
| Datum sax_subset | ( | PG_FUNCTION_ARGS | ) |
extract subset of SAX string.
It returns SAX string starts at offset and spanning length points. If offset is negative SAX string will be padded with NULL values in the beginning. If offset+length greater than length of original SAX string, result will be padded with NULL values at the end.
