History

- New in version 2.0.0

## Examples

Everything is lower case so nothing needs to be quoted.

    SELECT pgr_quote_ident('the_geom');

    pgr_quote_ident
    ---------------
       the_geom
    (1 row)

    SELECT pgr_quote_ident('public.edge_table');

      pgr_quote_ident
    -------------------
     public.edge_table
    (1 row)

The column is upper case so its double quoted.

    SELECT pgr_quote_ident('edge_table.MYGEOM');

       pgr_quote_ident
    -------------------
     edge_table."MYGEOM"
    (1 row)

    SELECT pgr_quote_ident('public.edge_table.MYGEOM');

           pgr_quote_ident
    ---------------------------
     public.edge_table."MYGEOM"
    (1 row)

The schema name has a capital letter so its double quoted.

    SELECT pgr_quote_ident('Myschema.edge_table');

        pgr_quote_ident
    ----------------------
     "Myschema".edge_table
    (1 row)

Ignores extra `.` separators.

    SELECT pgr_quote_ident('Myschema...edge_table');

       pgr_quote_ident
    ---------------------
     "Myschema".edge_table
    (1 row)
