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)
