[postgis-devel] Correction to documentation for estimated_extent()

[strk at refractions.net]

I meant differences between postgresql verisons, not postgis.
Would be nice (but a big work) to report introduction version
for every function. The manual currently always refers to latest
release.

This is how I changed the estimated_extent() entry:

   estimated_extent([schema], table, geocolumn)

    Return the 'estimated' extent of the given spatial table. The estimated is taken from the geometry column's statistics. The current schema will be used if not specified.

    For PostgreSQL>=8.0.0 statistics are gathered by VACUUM ANALYZE and resulting extent will be about 95% of the real one.

    For PostgreSQL<8.0.0 statistics are gathered by update_geometry_stats() and resulting extent will be exact.
