[postgis-devel] does unparse_WKT thread safe?

[xie_jiong]

Hi all,

   If two session execute following sql at same time, will postgis cause error?

   select st_astext(shape) from geotable;

   I just read the code and found that the funtion unparse_WKT uses static var out_start and out_pos, so if two session involk it in parallel, and I think the static vars will conflict. Is it true?

   Thanks!

Jiong
