简而言之,我的问题是"为什么$ libdir不能在我的PSQL安装上运行."

CREATE FUNCTION st_box2d_in(cstring) RETURNS box2d
    AS '$libdir/liblwgeom', 'BOX2DFLOAT4_in'
    LANGUAGE c IMMUTABLE STRICT;

产生错误

could not access file "$libdir/liblwgeom": No such file or directory

而

CREATE FUNCTION st_box2d_in(cstring) RETURNS box2d
    AS '/usr/local/pgsql/lib/liblwgeom', 'BOX2DFLOAT4_in'
    LANGUAGE c IMMUTABLE STRICT;

工作正常.

的输出

% pg_config --pkglibdir
/usr/local/pgsql/lib

似乎是正确的.
