Tsearch case sensitive with dotted search terms.


Hi,

I think when search terms have "."s in them they become case sensitive
in tsearch searches. How can we make them insensitive?

Use tsearch2, tsearch is marked as obsolet :)
More serious: apply attached patch, recompile and reinstall contrib/tsearch
module. Patch commited to 7.3,7.4 and 7.5 branches, it fix asymetrical lexeme
processing for text and query.
