Searching for Boyer-Moore in the manual, one  only finds the following line (in the 8.4 release
notes):

"Improve the performance of text_position() and related functions by using Boyer-Moore-
Horspool searching (David Rowley)"

I have two questions:

1. Where in postgres is the Boyer-Moore algorithm used?  (What happened to text_position() anyway?)

2. Shouldn't there be, for 'advocacy' reasons, a mention of this well-known algorithm in the
manual proper?  (I can make a doc-patch if needed)


Thanks,


Erik Rijkers
