Hi,  
i have installed Dolibarr V12.0.5 on linux with Nginx and Postgresql, but i had some problems (  
[Related topic](https://www.dolibarr.org/forum/t/dolibarr-on-linux-with-nginx-and-postgresql/22271) ),  
so i decided to upgrade it to V15.0.1, i downloaded files and followed the instructions, it first upgradet to V13, but when i want to upgrade it to V14 i had errors like;

`ERROR DB_ERROR_42804: ALTER TABLE llx_product_fournisseur_price MODIFY COLUMN packaging real DEFAULT NULL; ERROR: 42804: column "packaging" cannot be cast automatically to type real HINT: You might need to specify "USING packaging::real". LOCATION: ATPrepAlterColumnType, tablecmds.c:11681`

Seems fixed in v15.0.3  
For 15.01, you can run manually  
`ALTER TABLE llx_product_fournisseur_price MODIFY COLUMN packaging real DEFAULT NULL USING packaging::real;`
