Second argument to metaphone is suposed to set the limit on the number
of characters to return, but it breaks on some phrases:
usps=# select metaphone(a,3),metaphone(a,4),metaphone(a,20) from (select 'Hello world'::varchar AS a) a;
HLW | HLWR | HLWRLT
usps=# select metaphone(a,3),metaphone(a,4),metaphone(a,20) from (select 'A A COMEAUX MEMORIAL'::varchar AS a) a;
AKM | AKMKS | AKMKSMMRL
In every case I've found that does this, the 4th and 5th letters are
always 'KS'.
