 If I change sql to:

 {{{
 SELECT
 c1 AS "geom",
 c2 AS """""quoteColumn"
 FROM t1
 }}}

 I got different error:

 {{{
 Error executing main scan query: ERROR:  column ""quoteColumn" does not
 exist
 LINE 1: DECLARE cur CURSOR FOR SELECT """quoteColumn",ST_AsEWKB(ST_S...
                                       ^
 HINT:  Perhaps you meant to reference the column
 "__pgsql2shp22020_tmp_table.""quoteColumn".
 }}}

 I use `pgsql2shp RELEASE: 2.2.1 (r14555)` on Ubuntu 16.04 LTS and don't
 have any issues if column alias in sql doesn't contain double quotes.
