Dean Rasheed 53874c5228 Add pg_size_bytes() to parse human-readable size strings. 
This will parse strings in the format produced by pg_size_pretty() and
return sizes in bytes. This allows queries to be written with clauses
like "pg_total_relation_size(oid) > pg_size_bytes('10 GB')".

Robert Haas 8a1fab36ab pg_size_pretty: Format negative values similar to positive ones. 
Previously, negative values were always displayed in bytes, regardless
of how large they were.
